It’s a major international mystery with global consequences: Who was behind the explosions that damaged the Nord Stream gas pipelines last year in the Baltic Sea?

The answer has broad implications for European energy security but could also threaten Western unity over backing Ukraine in defending itself from Russia’s invasion. Or, it might shatter Russian and Chinese attempts to fix the blame on a hypocritical West, said The Associated Press.

Yet, nearly six months after the sabotage on the Russia-to-Germany pipelines, there is no accepted explanation. And a series of unconfirmed reports variously accusing Russia, the United States and Ukraine are filling an information vacuum as investigations into the blasts continue.

A look at the pipelines and what’s known about the explosions.

WHAT ARE THE NORD STREAM PIPELINES?

The pipelines, known as Nord Stream 1 and Nord Stream 2, are majority-owned by Russia's state-run energy giant Gazprom and used to transport natural gas from Russia to Europe under the Baltic to their termini in Germany.

Nord Stream 1 was completed and came online in 2011. Nord Stream 2 was not finished until the fall of 2021 but never became operational due to the launch of Russia's invasion of Ukraine in February, 2022.

WHY ARE THEY CONTROVERSIAL?

Both pipelines bypass existing routes that go through Ukraine, meaning not only that Ukraine loses income from transit fees but is unable to directly use the gas they carry.

Of perhaps greater concern to the West, the pipelines were seen as a move by Russia to gain further, if not almost complete, control over Europe's energy supplies. Many in the West fear that Russia will use energy as a political weapon against European countries as it has done in the past with former Soviet states.

Despite those concerns and over the objections of the Obama, Trump and Biden administrations, the German government under former Chancellor Angela Merkel moved ahead with the construction of the Nord Stream 2 project. The Biden administration waived sanctions against German entities involved in Nord Stream 2 after securing a pledge from Germany that it would allow backflows of gas into Ukraine and would act to shut the pipeline down should Russia try to use it to force political concessions.

After Russia's Feb. 24, 2022, invasion of Ukraine, Germany withdrew permission for Nord Stream 2, which had not yet come online.

WHAT HAPPENED TO THE PIPELINES?

First, Gazprom halted gas flows through Nord Stream 1 on Sept. 2, 2022, citing issues related to European sanctions imposed against Russia over the war in Ukraine.

Three weeks later, both Nord Stream 1 and Nord Stream 2 were hit by explosions that rendered them inoperable and caused significant leaks of gas that was idle in the pipelines. Some have said the blasts caused the worst release of methane in history, although the full extent of the environmental damage remains unclear.

The depth of the pipeline and the complexity of using underwater explosives lent credence to the idea that only a state actor with the expertise to handle such an operation could be responsible. But no one claimed responsibility.

In the immediate aftermath of the explosions, U.S. officials suggested Russia may have been to blame while Russia accused the United States and Britain of being behind them. Investigations by European nations, including Denmark, through whose waters the pipeline travels, and Germany have yet to yield conclusive results.

WHAT THEORIES HAVE BEEN REPORTED?

After months of few developments in the probes, American investigative journalist Seymour Hersch, known for past exposes of U.S. government malfeasance, self-published a lengthy report in February alleging that President Joe Biden had ordered the sabotage, which Hersch said was carried out by the CIA with Norwegian assistance.

That report, based on a single, unidentified source, has been flatly denied by the White House, the CIA and the State Department, and no other news organization has been able to corroborate it. Russia, followed by China, however, leaped on Hersch's reporting, saying it was grounds for a new and impartial investigation conducted by the United Nations.

On Tuesday, though, The New York Times, The Washington Post and German media published stories citing U.S. and other officials as saying there was evidence Ukraine, or at least Ukrainians, may have been responsible. The Ukrainian government has denied involvement.

Germany's Die Zeit newspaper and German public broadcasters ARD and SWR reported that investigators believed that five men and a woman used a yacht hired by a Ukrainian-owned company in Poland to carry out the attack. German federal prosecutors confirmed that a boat was searched in January but have not confirmed the reported findings.

WHAT ARE THE CONSEQUENCES FOR THOSE FOUND RESPONSIBLE?

The implications of a determination that Ukraine was behind the explosions are not entirely clear. It's unlikely it would result in an immediate loss of Western support for Ukraine in the war with Russia, but it might dampen enthusiasm for future assistance if it was found that Ukraine or its agents carried out such an operation in European waters.

A determination that the United States or a proxy was responsible would give Russia and China additional leverage to go after the U.S. and its allies as hypocrites in their demands for the rule of the law, sovereignty and territorial integrity to be respected.

A finding that Russia was behind the explosions would lend weight to Western claims that Moscow is in flagrant breach of international law and willing to use energy as a weapon against Europe.

There is no indication of when the European investigations will be complete — and it seems improbable, given the animosity and mistrust surrounding the Ukraine conflict, that its findings will be universally accepted.

The UN human rights chief said on ​Tuesday that he was "horrified" by mounting violence by Iran's security forces against peaceful protesters, with the UN citing its own sources as saying that hundreds have been killed so far.

The country's clerical authorities are ‌facing the biggest ‌demonstrations since 2022 ‌and ⁠on ​Sunday ‌a rights group said that unrest has killed more than 500 people. An Iranian official indicated on Tuesday it was higher, at around 2,000.

"This cycle of horrific violence cannot continue. The Iranian people and ⁠their demands for fairness, equality and justice must ‌be heard," UN High ‍Commissioner for ‍Human Rights Volker Turk said in a ‍statement read out by UN rights office spokesperson Jeremy Laurence.

Asked to comment on the scale of the killings, Laurence, citing ​the United Nations' sources in Iran, said: "The number that we're hearing is ⁠hundreds."

Turk also voiced concern that the death penalty might be used against thousands of protesters who have been arrested.

The unrest has prompted US President Donald Trump to reissue threats to intervene militarily on behalf of Iran's protesters.

"There's concern that (the protests) have been instrumentalized, and they shouldn't be instrumentalized by anyone," ‌said Laurence on a possible US intervention.

Russia battered Ukraine with more than two dozen missiles and hundreds of drones early Tuesday, killing four people and pummelling another power plant, piling more pressure on Ukraine's brittle energy system.

An AFP journalist in the eastern Kharkiv region, where four people were killed, saw firefighters battling a fire at a postal hub and rescue workers helping survivors by lamp light in freezing temperatures.

Ukrainian President Volodymyr Zelensky said "several hundred thousand" households near Kyiv were without power after the strikes, and again called on allies to bolster his country's air defense systems.

"The world can respond to this Russian terror with new assistance packages for Ukraine," President Volodymyr Zelensky wrote on social media.

"Russia must come to learn that cold will not help it win the war," he added.

Authorities in Kyiv and the surrounding region rolled out emergency power cuts in the hours after the attack, saying freezing temperatures were complicating their work.

DTEK, Ukraine's largest energy provider, said Russian forces had struck one of its power plants, saying it was the eighth such attack since October.

The operator did not reveal which of its plants was struck, but said Russia had attacked its power plants over 220 times since Moscow invaded Ukraine in 2022.

Moscow has pummelled Ukraine with daily drone and missile barrages in recent months, targeting energy infrastructure and cutting power and heating in the frigid height of winter.

The Ukrainian air force said that Tuesday's bombardment included 25 missiles and 247 drones.

The Kharkiv governor gave the death toll and added that six people were wounded in the overnight hit outside the region's main city, also called Kharkiv.

White helmeted emergency workers could be seen clambering through the still-smoking wreckage of a building occupied by postal company Nova Poshta, in a video posted by the regional prosecutor's office.

Within Ukraine's second city, Kharkiv Mayor Igor Terekhov said a Russian long-range drone struck a medical facility for children, causing a fire. No casualties were reported.

The overnight strikes hit other regions as well, including the southern city of Odesa.

Residential buildings, a hospital and a kindergarten were damaged, with at least five people wounded in two waves of attacks, regional governor Sergiy Lysak said.

Russia's use last week of a nuclear-capable Oreshnik ballistic missile on Ukraine sparked condemnation from Kyiv's allies, including Washington, which called it a "dangerous and inexplicable escalation of this war".

Moscow on Monday said the missile hit an aviation repair factory in the Lviv region and that it was fired in response to Ukraine's attempt to strike one of Russian President Vladimir Putin's residences -- a claim Kyiv denies and that Washington has said it does not believe happened.

The Israeli military said on Tuesday it continues to be “on alert for surprise scenarios” due to the ongoing protests in Iran, but has not made any changes to guidelines for civilians, as it does prior to a concrete threat.

“The protests in Iran are an internal matter,” Israeli military spokesperson Brig. Gen. Effie Defrin wrote on X.

Also on Tuesday, Iranian security forces arrested what a state television report described as terrorist groups linked to Israel in the southeastern city of Zahedan.

The report, without providing additional details, said the group entered through Iran’s eastern borders and carried US-made guns and explosives that the group had planned to use in assassinations and acts of sabotage.

Israel attacked Iran’s nuclear program over the summer, resulting in a 12-day war that killed nearly 1,200 Iranians and almost 30 Israelis. Over the past week, Iran has threatened to attack Israel if Israel or the US attacks.
