German authorities have issued a European arrest warrant for a Ukrainian man, identified as 'Volodymyr Z', suspected of involvement in the 2022 Nord Stream pipeline explosions. The suspect, last known to be in Poland, reportedly left the country before he could be detained and crossed into Ukraine. The arrest warrant, issued in June, represents a potential breakthrough in the investigation into the sabotage that damaged the pipelines between Russia and Germany. German media reports suggest the suspect is a diving instructor believed to have planted explosives on the pipelines from a yacht. Polish authorities confirmed receiving the warrant but failed to apprehend the suspect. The incident has heightened tensions amid the ongoing Russia-Ukraine conflict, with both sides previously blaming each other for the blasts.
