Quick Summary

A former Ukrainian army officer is set to go on trial in Hamburg, Germany, for his alleged role in sabotaging the Nord Stream natural gas pipelines in September 2022. Prosecutors charge him with causing an explosion and damaging property by organizing at least four bomb detonations near the Danish island of Bornholm that ruptured both operational and suspended pipelines under the Baltic Sea. The trial will examine whether Ukrainian state security agencies were involved, despite Ukraine’s close alliance with Germany; strict security measures have been implemented for the proceedings.

Story summary

A Ukrainian former military officer goes on trial in Hamburg, Germany this week for alleged sabotage of the Nord Stream gas pipelines on September 26, 2022. Prosecutors charge him with causing an explosion and committing a war crime by attacking civilian infrastructure. The suspect, referred to as Serhii K., denies involvement; he was extradited from Italy last year after being identified as Serhii Kuznetsov during extradition proceedings. Despite initial suspicions pointing towards Russia, evidence now increasingly implicates Ukrainian state security agencies in the attack, raising tensions between Ukraine and Germany due to their close alliance. The trial is highly sensitive politically and proceeds under strict security measures at the Hanseatic Higher Regional Court.
