German Chancellor Friedrich Merz suggested Poland is “probably right” in suspecting Russian involvement in the recent train blasts, citing patterns of past sabotage and espionage attempts. At the European Digital Sovereignty Summit in Berlin, Merz said he will seek further insights from Poland. French President Emmanuel Macron condemned the attacks but avoided speculating, instead warning that the blasts threaten crucial supply routes for aid to Ukraine. Polish authorities linked two suspects — a Ukrainian previously convicted of sabotage and a Donbass resident — both entering from Belarus before the explosions. The Warsaw–Lublin line remains vital for military and humanitarian transit.
