German authorities arrested a Ukrainian national near Rimini, Italy, in connection with the September 2022 sabotage of the Nord Stream 1 and 2 pipelines. The suspect, identified as Serhii K., is believed to have been part of a group that planted explosives. The pipelines, carrying Russian gas to Europe, were damaged by underwater explosions. While no one initially claimed responsibility, the attack was viewed as sabotage by both Russia and the West. The Ukrainian government denies involvement. The arrest is considered a significant breakthrough in the investigation.
