Russian Foreign Minister Sergei Lavrov said on Wednesday it appeared no European countries were conducting a proper investigation into the series of explosions that ruptured the Nord Stream gas pipelines in September.

"After the explosions on Nord Stream - which, it appears nobody in the European Union is going to objectively investigate - Russia stopped gas transportation through the northern routes," Lavrov said on Wednesday.

Russia has blamed Britain for the explosions - claims rejected by London - while investigators in Sweden and Denmark said they were the deliberate results of sabotage, though did not name any possible culprits.
