Russia says British navy personnel blew up Nord Stream gas pipelines

Reuters:  Russia's defence ministry said on Saturday that British navy personnel blew up the Nord Stream gas pipelines last month, directly accusing a leading NATO member of sabotaging critical Russian infrastructure.

The defence ministry did not give evidence for its claim. It said that "British specialists" from the same unit directed Ukrainian drone attacks on ships of Russian Black Sea fleet in Crimea earlier on Saturday that it said were largely repelled by Russian forces, with minor damage to a Russian minesweeper.

"According to available information, representatives of this unit of the British Navy took part in the planning, provision and implementation of a terrorist attack in the Baltic Sea on September 26 this year - blowing up the Nord Stream 1 and Nord Stream 2 gas pipelines," the ministry said.

Britain's defence ministry declined immediate comment when asked by Reuters about the Russian claim.

A sharp drop in pressure on both pipelines was registered on Sept. 26 and seismologists detected explosions, triggering a wave of speculation about sabotage to one of Russia's most important energy corridors.

Reuters has not been able to verify any of the conflicting claims about who was to blame for the damage.

Russia has previously blamed the West for the explosions that ruptured the Russian-built Nord Stream 1 and Nord Stream 2 pipelines on the bed of the Baltic Sea.

But Russia had not previously given specific details of who it thinks was responsible for the damage to the pipelines, previously the largest routes for Russian gas supplies to Europe.

PIPELINE MYSTERY

Sweden and Denmark have both concluded that four leaks on Nord Stream 1 and 2 were caused by explosions, but have not said who might be responsible. NATO Secretary-General Jens Stoltenberg has called the damage an act of sabotage.

Sweden has ordered additional investigations to be carried out into the damage done to the pipelines, the prosecutor in charge of the case said in a statement on Friday.

The Kremlin has repeatedly said allegations of Russian responsibility for the damage were "stupid" and Russian officials have said Washington had a motive as it wants to sell more liquefied natural gas (LNG) to Europe.

The United States has denied involvement.

The Nord Stream 1 and Nord Stream 2 pipelines have a joint annual capacity of 110 billion cubic metres - more than half of Russia's normal gas exports volumes.

Sections of the 1,224-km (760-mile) long pipelines, which run from Russia to Germany, lie at a depth of around 80-110 metres.

Russia said Ukrainian forces attacked ships from the Black Sea Fleet in Sevastopol, the biggest city in Russian-annexed Crimea, in the early hours of Saturday.

"Nine unmanned aerial vehicles and seven autonomous marine drones were involved in the attack," the defence ministry said.

"The preparation of this terrorist act and the training of servicemen of the Ukrainian 73rd Special Center for Naval Operations were carried out under the guidance of British specialists located in the town of Ochakiv."

All the air drones were destroyed though minor damage was done to the minesweeper Ivan Golubets. Sevastopol is the headquarters of Russia's Black Sea Fleet.
