The 'Smuggler' of Syrian Torture Archives Reveals His True Identity

For many years, the world only knew them by the aliases Caesar and Sami. Since 2014, these two names have been associated with documenting torture in Syrian prisons. The photos they smuggled out of Syria shook the world and prompted the United States to impose strict sanctions on the regime of former President Bashar al-Assad, under what became known as the “Caesar Act.”

These horrific photos documenting torture inflicted on detainees in Syrian prisons were used in courts in Western countries to convict Syrian officers on charges of torture and human rights violations.

But who is Sami, Ceasar’s “twin witness”?

In the first-ever interview he grants using his real name and photo, Sami revealed to “Asharq Al-Awsat” that he is Osama Othman, and that he is today head of the board of directors of the “Caesar Files Group Organization.”

He was working as a civil engineer when the Syrian revolution broke out in 2011, a revolution that began peacefully but quickly turned into a bloodbath after the forces of President Bashar al-Assad’s regime brutally suppressed it.

Sami lived in the Damascus countryside, which was divided between opposition factions and government forces. His area was under the control of factions that were part of what was known as the “Free Army,” but a person very close to him, who later became known as “Caesar,” was working in areas controlled by the regime forces. His job was not ordinary. His mission was to document deaths in Syrian security services departments. He documented them with photos: this body is missing a part of the head, this one is missing eyes, and that one has signs of severe torture. Some of the bodies showed signs of starvation.

He documented naked bodies with numbers. Thousands of photos. Women, men, and children. The crime of many of them was officially classified as “terrorism.” But how could a child’s crime be “terrorism”? The ugliness of the crimes prompted “Sami” and “Caesar” to work together to document what was happening in Syrian prisons and detention centers, specifically in Damascus, where “Caesar” worked and who sometimes documented the deaths of no less than 70 people a day. The two men began collaborating on collecting torture documents in May 2011. “Caesar” would smuggle the photos on a USB drive and give them to Sami in opposition areas.

“Dad... why are they sleeping without clothes?”

The “smuggler” of the Syrian torture archive is often reluctant to talk about himself and evades answering questions about his personal role in the story. However, after much persistence, he recounted a small portion of his experience. He told Asharq Al-Awsat: “Even my children did not know that they were the children of the man who carries the secret alias (Sami)... Once, as I was watching and searching for a photo among the evidence on my computer at night, I was surprised that my young son came to me and asked: Dad, why do these people sleep without clothes? In his innocence, he thought they were asleep. It is difficult to make your son live through this pain, so it was necessary for us to protect our children by protecting ourselves.”

Recalling his feelings at the time, he added: “When you make a very serious decision, why make others bear the responsibility for this decision? People you would not have consulted when you left. People who were only a few years old and people who were very old, you would’ve burdened them with fear without asking their permission at a moment when you decided that your responsibility was greater than your love for your family”.

The efforts of “Sami” and “Caesar” resulted in smuggling tens of thousands of photos of the bodies of torture victims out of Syria. The photos were revealed for the first time in 2014 after they left Syria. Today, the photos they smuggled have become part of the “indictment” against the security services that were affiliated with President Bashar al-Assad. In fact, the crimes were not limited to one prison or another. Torture practices were widespread in a way that leaves no doubt that it was a systematic policy adopted by the ruling regime, most likely with cover from the highest levels.

Asharq Al-Awsat asked Sami why he decided to break his silence and reveal his real name. He replied: “The Syrians know the answer to this question. I think the answer is obvious for most Syrians who were inside Syria and those who were outside it. The nature of the work and the nature of the documents that we left Syria with, which went through complex stages and many steps until we reached this blessed day, was the reason I was keen to hide my identity and the identity of many of the team members.

He added: “Today, thank God, we are in a completely different situation. We are in another place. In a new Syria. I wanted the Syrians to know what happened, and I also addressed them and the authorities in Damascus with what we hope the situation will be regarding the legal issues related to documenting and archiving data and evidence that will lead us to a stage of accountability and transitional justice to achieve stability in Syrian society. I think this matter deserves that we come out to tell the world what information and ideas we have so that we do not fall into the same problem in future generations.”

Sami adds: “I did not think, in truth, that I would live to say this word. Congratulations to our people in Syria on the fall of Assad. Congratulations to all the honorable people in this world on the fall of Assad. Thanks to everyone who stood with our revolution and shame on everyone who stood against it. After 14 years of working in secret and facing fear and anxiety, the sun of long-awaited freedom is now shining on Syria, for which our people paid a heavy price. A team of unknown heroes led a complex work full of dangers, that were not solely emanating from the regime. Today, they pledge to Syria to continue defending the dignity of the Syrian human being wherever he may be.”

The importance of accountability

Sami stressed the importance of “accountability” in Syria today, after the overthrow of the former regime, and says: “In this critical moment that Syria is going through as it prepares to enter a new phase after more than five decades of the Assad family rule, we call on the (new) government to work hard to achieve justice, hold perpetrators accountable, and ensure the dignity of human rights as a basis for building a better future that all Syrians dream of.”

He added: “We have witnessed during the past few days, and the rapid events that preceded them, a noticeable increase in the possibility of chaos spreading as a result of the remnants of the Syrian regime. Citizens randomly entering prisons and detention centers have led to the destruction or loss of very important official documents and records that reveal violations dating back decades.” He stressed that “the full responsibility for the destruction of evidence and the loss of the rights of detainees and survivors lies with the security officials of the former regime who have left and those who are still carrying out their duties and responsibilities, in addition to the current forces that are preparing to take power in Damascus. Although what is happening now can be expected after the liberation of the country from the Syrian regime, swift intervention has become urgent in collecting evidence and documents from the previous archives of security institutions, ministries and other government institutions, and this is what raises our concern about the continued work of the regime’s employees, which enables them to obliterate and destroy files of importance in revealing the crimes of the defunct regime.”

Baath Party documents

Sami believes that “all the institutions of the former regime hold documents of extreme importance, whether security, civil or military, and we do not ignore our concern about the obliteration of documents in all the branches and annexes of the Baath Party, which all Syrians know were security institutions par excellence, and those in charge of them practiced all forms of physical and moral intimidation against our great people throughout the years of the revolution.”

He adds: “We hope that this step will be taken with the participation of human rights organizations concerned with following up on issues related to research and investigation into human rights violations. The delay in revealing the official and secret detention sites that may exist in the liberated areas or areas that the armed forces of the Syrian opposition did not reach, in addition to testimonies and information circulating about the transfer of detainees from different prisons to unknown places before the fall of the regime, and the failure to provide the necessary medical and humanitarian assistance to the survivors who were released in the past days, reflects a disregard for the lives of these individuals.”

Sami called on the current authorities to “take immediate and transparent steps to reveal the fate of detainees and victims who died under torture in Syrian prisons and to suspend all those responsible for managing and operating prisons to begin urgently and immediately providing documents that clarify the names and numbers of victims to ensure the families’ right to know the fate of their loved ones. The Syrian people's right to access the truth cannot be compromised and is a duty of all concerned parties. Tolerating perpetrators of crimes under any pretext constitutes a clear violation of humanitarian and legal standards, and gives the green light to reproduce the tools of repression and violations that were practiced by the security services and are still in place.”

The Syrian human rights activist stressed that “achieving justice requires holding accountable all those involved in the crimes committed against the Syrian people, and achieving peace and stability in Syria depends on transitional justice as a fundamental principle at this stage. We call for a national reconciliation based on the principles of justice and accountability that guarantees the rights of all components of the Syrian people in a safe and stable environment that respects their dignity and meets their needs while ensuring that there is no impunity under any name.”

Opposition “imposed” on the people

Sami criticized parties in the Syrian opposition without specifying them, speaking about “failures” they had experienced. He said: “In light of the previous political failures of the opposition that were imposed on the Syrian people, we stress the need to make immediate reassuring statements about the vision and how to involve the people in decision-making and begin the process of building society in a way that respects the will of the Syrian people and guarantees their right to self-determination.”

He called on the current authority to consolidate and facilitate the work of all civil society institutions operating inside and outside Syria. “We also call on all of them to support efforts to achieve transitional justice in Syria effectively and to involve the Syrian people in developments on a regular basis, and to contribute to providing humanitarian and medical support to survivors of arrest and enforced disappearance, and to ensure that all those involved in crimes are held accountable and that impunity is not allowed.”

Sami also called for publishing and disseminating the names of the officers responsible for crimes against the Syrian people, and to monitor official and unofficial crossings, “as well as call on the official Syrian media institutions that have always contributed to the oppression of Syrians by distorting facts and glorifying the killers, to return to their natural function as a tool that strengthens the citizen's confidence in state institutions and a source of correct information”.

He adds: “It pains us to see our people searching for the names of their missing loved ones on social media pages, while state media is absent from performing its mission for which it only exists as a non-politicized service institution."

Crimes without a statute of limitations

Sami stressed that "crimes against humanity and crimes of genocide do not expire with a statute of limitations and cannot be tolerated under any circumstances”. He continues: “The Syria we dream of is a free Syria based on justice and equality. Transitional justice that precedes comprehensive national reconciliation is the only way to build the Syria of the future. We are all hopeful that Syria will be fine now. The Syria that our team left 11 years ago with thousands of tortured faces and disfigured bodies. Hundreds of which were separated from their eyes, who dreamed of being among us today”.

“In one of those faces, I saw the image of my father, mother, brothers and friends. In the darkness of the long nights, I looked at those faces and promised them that we would win." He listed his comrades killed by the regime, Yahya Shorbaji (a human rights activist), Ghiath Matar, Abdullah Othman, Burhan Ghadhban, and Nour al-Din Zaatar, saying: "To all of them, those I knew and those I did not know, may God have mercy on you. We have won (...) and Assad has fallen. May God have mercy on you and may the curse of history be upon Assad."

Unknown Heroes Behind Caesar

Sami refused to provide information about how he and Caesar left Syria and reached Western countries. However, he simply said, in response to a question: “I am Osama Othman, a civil engineer from the Damascus countryside. Many people know me even though I hide under the name (Sami). I had to use it as a shield to protect me during the period of hard work on these complex files that many unknown heroes contributed to creating.”

He added: “I am not the only one. There are many unknown heroes who contributed to getting us to this stage. The Caesar files required tremendous efforts in Europe through the courts, and in the United States through Syrian organizations that made tremendous efforts until they were able to push the US administration to issue what is called the Caesar Act or the Civilian Protection Act.”



Is Iran Pushing Houthis Toward Military Action Against Washington?

Is Iran Pushing Houthis Toward Military Action Against Washington?

As US military movements intensify in the Middle East and the possibility of strikes on Iran looms, Yemen’s Houthi group has continued military preparations, mobilizing fighters and establishing new weapons sites.

The Houthi mobilization comes at a time when the group is widely viewed as one of Iran’s most important regional arms for retaliation.

Although the Iran-backed group has not issued any official statement declaring its position on a potential US attack on Iran, its leaders have warned Washington against any military action and against bearing full responsibility for any escalation and its consequences.

They have hinted that any response would be handled in accordance with the group’s senior leadership's assessment, after evaluating developments and potential repercussions.

Despite these signals, some interpret the Houthis’ stance as an attempt to avoid drawing the attention of the current US administration, led by President Donald Trump, to the need for preemptive action in anticipation of a potential Houthi response.

The Trump administration previously launched a military campaign against the group in the spring of last year, inflicting heavy losses.

Islam al-Mansi, an Egyptian researcher specializing in Iranian affairs, said Iran may avoid burning all its cards unless absolutely necessary, particularly given US threats to raise the level of escalation should any Iranian military proxies intervene or take part in a confrontation.

Iran did not resort to using its military proxies during its confrontation with Israel or during a limited US strike last summer because it did not perceive an existential threat, al-Mansi said.

That calculation could change in the anticipated confrontation, potentially prompting Houthi intervention, including targeting US allies, interests, and military forces, he told Asharq Al-Awsat.

Al-Mansi added that although Iran previously offered, within a negotiating framework, to abandon its regional proxies, including the Houthis, this makes it more likely that Tehran would use them in retaliation, noting that Iran created these groups to defend its territory from afar.

Many intelligence reports suggest that Iran’s Revolutionary Guard has discussed with the Houthis the activation of alternative support arenas in a potential US-Iran confrontation, including the use of cells and weapons not previously deployed.

Visible readiness

In recent days, Chinese media outlets cited an unnamed Houthi military commander as saying the group had raised its alert level and carried out inspections of missile launch platforms in several areas across Yemen, including the strategically important Red Sea region.

In this context, Yemeni political researcher Salah Ali Salah said the Houthis would participate in defending Iran against any US attacks, citing the group’s media rhetoric accompanying mass rallies, which openly supports Iran’s right to defend itself.

While this rhetoric maintains some ambiguity regarding Iran, it repeatedly invokes the war in Gaza and renews Houthi pledges to resume military escalation in defense of the besieged enclave’s population, Salah told Asharq Al-Awsat.

He noted that Iran would not have shared advanced and sophisticated military technologies with the Houthis without a high degree of trust in their ability to use them in Iran’s interest.

In recent months, following Israeli strikes on the unrecognized Houthi government and several of its leaders, hardline Houthi figures demonstrating strong loyalty to Iran have become more prominent.

On the ground, the group has established new military sites and moved equipment and weapons to new locations along and near the coast, alongside the potential use of security cells beyond Yemen’s borders.

Salah said that if the threat of a military strike on Iran escalates, the Iranian response could take a more advanced form, potentially including efforts to close strategic waterways, placing the Bab al-Mandab Strait within the Houthis’ target range.

Many observers have expressed concern that the Houthis may have transferred fighters and intelligence cells outside Yemen over recent years to target US and Western interests in the region.

Open options

After a ceasefire was declared in Gaza, the Houthis lost one of their key justifications for mobilizing fighters and collecting funds. The group has since faced growing public anger over its practices and worsening humanitarian conditions, responding with media messaging aimed at convincing audiences that the battle is not over and that further rounds lie ahead.

Alongside weekly rallies in areas under their control in support of Gaza, the Houthis have carried out attacks on front lines with Yemen’s internationally recognized government, particularly in Taiz province.

Some military experts describe these incidents as probing attacks, while others see them as attempts to divert attention from other activities.

In this context, Walid al-Abara, head of the Yemen and Gulf Studies Center, said the Houthis entered a critical phase after the Gaza war ended, having lost one of the main justifications for their attacks on Red Sea shipping.

As a result, they may seek to manufacture new pretexts, including claims of sanctions imposed against them, to maintain media momentum and their regional role.

Al-Abara told Asharq Al-Awsat that the group has two other options. The first is redirecting its activity inward to strengthen its military and economic leverage, either to impose its conditions in any future settlement or to consolidate power.

The second is yielding to international and regional pressure and entering a negotiation track, particularly if sanctions intensify or its economic and military capacity declines.

According to an assessment by the Yemen and Gulf Studies Center, widespread protests in Iran are increasingly pressuring the regime’s ability to manage its regional influence at the same pace as before, without dismantling its network of proxies.

This reality is pushing Tehran toward a more cautious approach, governed by domestic priorities and cost-benefit calculations, while maintaining a minimum level of external influence without broad escalation.

Within this framework, al-Abara said Iran is likely to maintain a controlled continuity in its relationship with the Houthis through selective support that ensures the group remains effective.

However, an expansion of protests or a direct military strike on Iran could open the door to a deeper Houthi repositioning, including broader political and security concessions in exchange for regional guarantees.

As the bodies of two dozen Palestinians killed in Israeli strikes arrived at hospitals in Gaza on Wednesday, the director of one asked a question that has echoed across the war-ravaged territory for months.

“Where is the ceasefire? Where are the mediators?” Shifa Hospital's Mohamed Abu Selmiya wrote on Facebook.

At least 556 Palestinians have been killed in Israeli strikes since a US-brokered truce came into effect in October, including 24 on Wednesday and 30 on Saturday, according to Gaza's Health Ministry. Four Israeli soldiers have been killed in Gaza in the same period, with more injured, including a soldier whom the military said was severely wounded when militants opened fire near the ceasefire line in northern Gaza overnight.

Other aspects of the agreement have stalled, including the deployment of an international security force, Hamas' disarmament and the start of Gaza's reconstruction. The opening of the Rafah border crossing between Gaza and Egypt raised hope of further progress, but fewer than 50 people were allowed to cross on Monday, The Associated Press said.

Hostages freed as other issues languish In October, after months of stalled negotiations, Israel and Hamas accepted a 20-point plan proposed by US President Donald Trump aimed at ending the war unleashed by Hamas' Oct. 7, 2023, attack into Israel.

At the time, Trump said it would lead to a “Strong, Durable, and Everlasting Peace."

Hamas freed all the living hostages it still held at the outset of the deal in exchange for thousands of Palestinian prisoners held by Israel and the remains of others.

But the larger issues the agreement sought to address, including the future governance of the strip, were met with reservations, and the US offered no firm timeline.

The return of the remains of hostages meanwhile stretched far beyond the 72-hour timeline outlined in the agreement. Israel recovered the body of the last hostage only last week, after accusing Hamas and other militant groups of violating the ceasefire by failing to return all of the bodies. The militants said they were unable to immediately locate all the remains because of the massive destruction caused by the war — a claim Israel rejected.

The ceasefire also called for an immediate influx of humanitarian aid, including equipment to clear rubble and rehabilitate infrastructure. The United Nations and humanitarian groups say aid deliveries to Gaza's 2 million Palestinians have fallen short due to customs clearance problems and other delays. COGAT, the Israeli military body overseeing aid to Gaza, has called the UN's claims “simply a lie.”

Ceasefire holds despite accusations

Violence has sharply declined since the ceasefire paused a war in which more than 71,800 Palestinians have been killed, according to the Gaza Health Ministry. The ministry is part of the Hamas-led government and maintains detailed records seen as generally reliable by UN agencies and independent experts.

Hamas-led militants killed some 1,200 people in the initial October 2023 attack and took around 250 hostage.

Both sides say the agreement is still in effect and use the word “ceasefire” in their communications. But Israel accuses Hamas fighters of operating beyond the truce line splitting Gaza in half, threatening its troops and occasionally opening fire, while Hamas accuses Israeli forces of gunfire and strikes on residential areas far from the line.

Palestinians have called on US and Arab mediators to get Israel to stop carrying out deadly strikes, which often kill civilians. Among those killed on Wednesday were five children, including two babies. Hamas, which accuses Israel of hundreds of violations, called it a “grave circumvention of the ceasefire agreement.”

In a joint statement on Sunday, eight Arab and Muslim countries condemned Israel’s actions since the agreement took effect and urged restraint from all sides “to preserve and sustain the ceasefire.”

Israel says it is responding to daily violations committed by Hamas and acting to protect its troops. “While Hamas’ actions undermine the ceasefire, Israel remains fully committed to upholding it,” the military said in a statement on Wednesday.

“One of the scenarios the (military) has to be ready for is Hamas is using a deception tactic like they did before October 7 and rearming and preparing for an attack when it’s comfortable for them,” said Lt. Col. Nadav Shoshani, a military spokesperson.

Some signs of progress

The return of the remains of the last hostage, the limited opening of the Rafah crossing, and the naming of a Palestinian committee to govern Gaza and oversee its reconstruction showed a willingness to advance the agreement despite the violence.

Last month, US envoy Steve Witkoff, who played a key role in brokering the truce, said it was time for “transitioning from ceasefire to demilitarization, technocratic governance, and reconstruction.”

That will require Israel and Hamas to grapple with major issues on which they have been sharply divided, including whether Israel will fully withdraw from Gaza and Hamas will lay down its arms.

Though political leaders are holding onto the term “ceasefire” and have yet to withdraw from the process, there is growing despair in Gaza.

On Saturday, Atallah Abu Hadaiyed heard explosions in Gaza City during his morning prayers and ran outside to find his cousins lying on the ground as flames curled around them.

“We don’t know if we’re at war or at peace,” he said from a displacement camp, as tarpaulin strips blew off the tent behind him.


What to Know as Iran and US Set for Nuclear Talks in Oman

What to Know as Iran and US Set for Nuclear Talks in Oman

Iran and the United States will hold talks Friday in Oman, their latest over Tehran's nuclear program after Israel launched a 12-day war on the country in June and Iran launched a bloody crackdown on nationwide protests.

US President Donald Trump has kept up pressure on Iran, suggesting America could attack Iran over the killing of peaceful demonstrators or if Tehran launches mass executions over the protests. Meanwhile, Trump has pushed Iran's nuclear program back into the frame as well after the June war disrupted five rounds of talks held in Rome and Muscat, Oman, last year.

Trump began the diplomacy initially by writing a letter last year to Iran’s 86-year-old Supreme Leader Ali Khamenei to jump start these talks. Khamenei has warned Iran would respond to any attack with an attack of its own, particularly as the theocracy he commands reels following the protests.

Here’s what to know about Iran’s nuclear program and the tensions that have stalked relations between Tehran and Washington since the 1979 Iranian Revolution.

Trump writes letter to Khamenei Trump dispatched the letter to Khamenei on March 5, 2025, then gave a television interview the next day in which he acknowledged sending it. He said: “I’ve written them a letter saying, ‘I hope you’re going to negotiate because if we have to go in militarily, it’s going to be a terrible thing.’”

Since returning to the White House, the president has been pushing for talks while ratcheting up sanctions and suggesting a military strike by Israel or the US could target Iranian nuclear sites.

A previous letter from Trump during his first term drew an angry retort from the supreme leader.

But Trump’s letters to North Korean leader Kim Jong Un in his first term led to face-to-face meetings, though no deals to limit Pyongyang’s atomic bombs and a missile program capable of reaching the continental US.

Oman mediated previous talks

Oman, a sultanate on the eastern edge of the Arabian Peninsula, has mediated talks between Iranian Foreign Minister Abbas Araghchi and US Mideast envoy Steve Witkoff. The two men have met face to face after indirect talks, a rare occurrence due to the decades of tensions between the countries.

It hasn't been all smooth, however. Witkoff at one point made a television appearance in which he suggested 3.67% enrichment for Iran could be something the countries could agree on. But that’s exactly the terms set by the 2015 nuclear deal struck under former President Barack Obama, from which Trump unilaterally withdrew America. Witkoff, Trump and other American officials in the time since have maintained Iran can have no enrichment under any deal, something to which Tehran insists it won't agree.

Those negotiations ended, however, with Israel launching the war in June on Iran.

The 12-day war and nationwide protests Israel launched what became a 12-day war on Iran in June that included the US bombing Iranian nuclear sites. Iran later acknowledged in November that the attacks saw it halt all uranium enrichment in the country, though inspectors from the International Atomic Energy Agency have been unable to visit the bombed sites.

Iran soon experienced protests that began in late December over the collapse of the country's rial currency. Those demonstrations soon became nationwide, sparking Tehran to launch a bloody crackdown that killed thousands and saw tens of thousands detained by authorities.

Iran’s nuclear program worries the West Iran has insisted for decades that its nuclear program is peaceful. However, its officials increasingly threaten to pursue a nuclear weapon. Iran now enriches uranium to near weapons-grade levels of 60%, the only country in the world without a nuclear weapons program to do so.

Under the original 2015 nuclear deal, Iran was allowed to enrich uranium up to 3.67% purity and to maintain a uranium stockpile of 300 kilograms (661 pounds). The last report by the International Atomic Energy Agency on Iran’s program put its stockpile at some 9,870 kilograms (21,760 pounds), with a fraction of it enriched to 60%.

US intelligence agencies assess that Iran has yet to begin a weapons program, but has “undertaken activities that better position it to produce a nuclear device, if it chooses to do so.” Iranian officials have threatened to pursue the bomb.

Decades of tense relations between Iran and the US Iran was once one of the US’s top allies in the Mideast under Shah Mohammad Reza Pahlavi, who purchased American military weapons and allowed CIA technicians to run secret listening posts monitoring the neighboring Soviet Union. The CIA had fomented a 1953 coup that cemented the shah’s rule.

But in January 1979, the shah, fatally ill with cancer, fled Iran as mass demonstrations swelled against his rule. The Iranian Revolution followed, led by Grand Khomeini, and created Iran’s theocratic government.

Later that year, university students overran the US Embassy in Tehran, seeking the shah’s extradition and sparking the 444-day hostage crisis that saw diplomatic relations between Iran and the US severed.

The Iran-Iraq war of the 1980s saw the US back Saddam Hussein. The “Tanker War” during that conflict saw the US launch a one-day assault that crippled Iran at sea, while the US later shot down an Iranian commercial airliner that the US military said it mistook for a warplane.

Iran and the US have seesawed between enmity and grudging diplomacy in the years since, with relations peaking when Tehran made the 2015 nuclear deal with world powers. But Trump unilaterally withdrew America from the accord in 2018, sparking tensions in the Mideast that persist today.
