Moscow may seek compensation for the damage caused by last year’s explosions on the Nord Stream gas pipelines, according to RIA Novosti, citing a Russian diplomat.

Last September, the pipelines that connect Russia and Germany beneath the Baltic Sea were hit by unexplained blasts, which Moscow described as an act of “international terrorism.”

“We do not rule out later the raising of the issue of compensation for damage as a result of the explosion of the Nord Stream gas pipelines,” Dmitry Birichevsky, the head of Russia’s Foreign Ministry department for economic cooperation, said in an interview with the news agency.

He added that Western countries were opposing a Russia-prepared draft U.N. Security Council resolution urging an independent international investigation of the Nord Stream blasts.

“Despite this, we intend to continue to insist on a comprehensive and open international investigation with the mandatory participation of Russian representatives,” Birichevsky said.
