Sergey K., a Ukrainian citizen, will be tried from October 14 in a court in Hamburg, Germany, on charges of aiding a war crime and destroying energy infrastructure. This trial comes after he was arrested in Italy in August 2025 and subsequently extradited to Germany.
Details of the Nord Stream attack
On September 26, 2022, aerial images from the Baltic Sea near the island of Bornholm were released showing large amounts of methane gas erupting. This incident is related to the explosion of three out of four Nord Stream 1 and 2 pipelines between Russia and Germany. The attack occurred seven months after Moscow's full-scale invasion of Ukraine and ended a major energy project between Germany and Russia in which both sides had invested billions of dollars.
Political and social implications
The attacks on Nord Stream meant the cessation of Germany's access to cheap Russian gas, but since the start of the Ukraine war, Russia had repeatedly limited or halted gas flows from Nord Stream 1. Meanwhile, Nord Stream 2 had not yet become operational. The accusation against Sergey K. as a Ukrainian citizen carries additional political sensitivities, as Germany continues its military and financial support for Ukraine and has accepted about 1.3 million Ukrainian refugees.
Critics of Germany's support for Ukraine, particularly far-right parties, are calling for improved relations with Moscow and an end to support for Ukraine. Some have informally tried Sergey K. and suspect that the political or military leadership of Ukraine was behind this attack.
However, some German military officials, including Commander Goran Svestic, believe that a state structure was likely behind this attack and claim that Ukraine is not seeking to jeopardize Germany's support.
Currently, discussions about Germany's support for Ukraine are intensifying, and public support for sending weapons to Ukraine has decreased. In the parliamentary elections in eastern German states, the far-right Alternative for Germany (AfD) has achieved significant successes, and polls indicate that this party is also leading nationally.
If Sergey K. is found guilty and a connection to the leadership of Ukraine is established, Germany will face a major dilemma. On one hand, judicial independence must be maintained, and on the other hand, the German government wants to prevent Russia from exploiting this case. Meanwhile, pressure on Germany from within the country will also significantly increase.
