Ukraine denies targeting Bulgarian pipeline after drone from Romania explodes

Ukraine denied intentionally targeting Bulgaria after a drone exploded Saturday near a gas pipeline shortly after entering Bulgarian airspace from Romania; no casualties or damage were reported. Bulgaria's defense ministry said the drone matched types used by Ukraine and was likely accidental; Ukraine said it was investigating and denied deliberate targeting. Prime Minister Rumen Radev said the drone went undetected, exploding near compressor stations on the Trans-Balkan pipeline. Since Russia's full-scale invasion, drones have repeatedly strayed into NATO airspace; earlier incidents occurred in Latvia, Estonia, Lithuania, Moldova and Romania, with officials often blaming Russian electronic warfare.
