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.

Iran on Monday summoned diplomats in Tehran representing France, Germany, Italy and the UK to object to what it described as support by those countries for the protests that have shaken the country, its foreign ministry said.

The diplomats were shown a video of the damage caused by "rioters" and told their governments should "withdraw official statements supporting the protesters", the ministry said in a statement quoted by state television.

In Paris, the French foreign ministry confirmed that "European ambassadors" had been summoned by Iran.

Iran's bazaar merchants, the trader class who were the financial backbone of the 1979 revolution, have turned against the clerics they helped bring to power, fueling unrest over an economy that has morphed into full-blown anti-government protests.

Frustration among bazaar merchants, from small-scale shopkeepers to large wholesale traders, has grown as their political and economic clout in Iran has diminished over the decades while the elite Revolutionary Guards have tightened their grip on the economy, building sprawling and tightly held networks of power.

"We are struggling. We cannot import goods because of US sanctions and because only the Guards or those linked to them control the economy. They only think about their own benefits," said a trader at Tehran’s centuries-old Grand Bazaar, speaking on condition of anonymity.

The wave of protests that has engulfed the country, posing one of the toughest challenges ever to the clerical leadership, erupted in late December in Tehran's Grand Bazaar, where hundreds of shopkeepers denounced the sharp fall in the rial currency.

The demonstrations quickly swelled and turned political, challenging the Islamic Republic's legitimacy. Protesters burned images of Supreme Leader Ali Khamenei and chanted "Death ‌to the dictator" - ‌undeterred by security forces armed with tear gas, batons, and, in many cases, live ammunition.

Iran’s ‌rulers, ⁠while acknowledging economic difficulties, have ‌blamed their longtime foes the US and Israel for fomenting the unrest. They appear intent on holding onto power at any cost, backed by a security apparatus refined over decades of suppressing ethnic revolts, student movements, and protests over economic hardship and social freedoms.

A combination of international sanctions and the Guards' sprawling economic empire has limited the government's ability to ease the dire economic situation.

Tehran-based analyst Saeed Laylaz said the government has lost control over the situation.

"What is striking is that the unrest began in the bazaar. For merchants, the core issue isn’t inflation - it’s price volatility, which leaves them unable to decide whether to buy or sell," he said.

Economic disparities between ordinary Iranians and the clerical and security elite, along with economic mismanagement and state corruption - ⁠reported even by state media - have fanned discontent at a time when inflation is pushing the price of many goods beyond the means of most people.

Iran's rial currency has lost nearly ‌half its value against the dollar in 2025, with official inflation reaching 42.5% in December.

CONTROL ‍OF SECTORS FROM OIL TO CONSTRUCTION

Created by the republic's ‍late founder Khomeini, the Guards first secured an economic foothold after the Iran-Iraq war in the 1980s, when clerical rulers allowed them ‍to invest in leading Iranian industries.

Their influence expanded exponentially over decades, benefiting from Khamenei's full backing and from opportunities created by Western sanctions, which effectively excluded Iran from the global financial and trading system.

The Guards now control vast sectors of the economy, from oil to transportation, communications, and construction.

Another trader said the crisis was not over, as the Guards have long proved adept at defending their economic interests.

"The government wants to resolve the problem, but it lacks the means and power in this system. The economy is not controlled by the government," said the trader, a 62-year-old carpet seller in Tehran.

All aspects of the country's sanctions-hit oil business have come under the growing influence of the ⁠Guards - from the shadow fleet of tankers that secretly ship sanctioned crude, to logistics and front companies selling the oil, mostly to China.

"No one knows how much of the oil money that the Guards get from selling Iran’s oil returns to the country ... they are too powerful to be questioned about it,” said a senior Iranian official, who asked not to be named.

During his 2013–2021 presidency, pragmatist Hassan Rouhani repeatedly clashed with the Guards, accusing them publicly of resisting budget cuts, while his attempts to curb their commercial networks and assets were largely frustrated.

THE ESTABLISHMENT RELIES ON THE GUARDS TO END UNREST

Even as it has relinquished economic power, the clerical establishment has relied on its loyal forces - the Guards and its affiliated Basij paramilitary - to violently crush ethnic uprisings, student unrest, and protests over economic hardship, preserving the political order.

"Given the sensitive circumstances when the country faces foreign threats, Khamenei cannot upset the Guards by curbing their economic influence. The establishment needs them to quell the protests and confront foreign threats," said an insider, close to Rouhani.

US-based rights group HRANA said it had verified the deaths of 544 people - 496 protesters and 48 security personnel - with 10,681 people arrested since ‌the protests began on December 28 and spread around the country. Reuters was unable to independently verify the tallies.

The authorities have not given numbers of casualties, but officials say many members of the security forces have been killed by "terrorists and rioters" linked to foreign foes, including the US States and Israel.

Greenland Says It Should Be Defended by NATO, Rejects Any US Takeover

Greenland's government said on Monday it will increase efforts to ensure the defense of the Arctic territory takes place under the auspices of NATO and again rejected US President Donald Trump's ambition to take over the island.

Trump has said the United States must own Greenland, an autonomous part of the Kingdom of Denmark, to prevent Russia ‌or China occupying the ‌strategically located and minerals-rich territory ‌in ⁠the future.

"All ‌NATO member states, including the United States, have a common interest in the defense of Greenland," the island's coalition government said in a statement, adding that it can in no way accept a US takeover of Greenland.

"As part of ⁠the Danish commonwealth, Greenland is a member of NATO and ‌the defense of Greenland ‍must therefore be through NATO," ‍the government said.

The European Union Commissioner ‍for Defense and Space Andrius Kubilius said earlier on Monday that any US military takeover of Greenland would be the end of NATO.

Trump first floated the idea of a US takeover of Greenland in 2019 during his first term ⁠in office, although he faces opposition in Washington, including from within his own party.

While Denmark has ruled Greenland for centuries, the territory has gradually been moving towards independence since 1979, a goal shared by all political parties elected to the island's parliament.

"We are a democratic society that makes our own decisions. And our actions are based on international law," Greenland's Prime Minister ‌Jens-Frederik Nielsen wrote on LinkedIn.
