European countries are investigating three mystery leaks in two major gas pipelines between Russia and Europe.
The cause of the damage to Nord Stream 1 and 2 is unclear, but authorities have not ruled out sabotage.
The operator of Nord Stream 1 said the undersea lines had simultaneously sustained “unprecedented” damage in one day.
Both pipelines have been flashpoints in the energy tussle between Moscow and Europe.
Whatever the cause of the damage, it won’t immediately affect the supply of gas to Europe as neither pipeline was operational.
The European Union has previously accused Russia of using a reduction in gas supplies to blackmail Europe, but Moscow denies this. It says sanctions against Russia make it impossible to properly maintain the gas infrastructure.
