MARIUPOL, Ukraine (AP) — Ukrainian troops and pro-Russia separatists clashed Friday in a southern port town, as the United States confirmed earlier reports that a convoy of armored vehicles including three T-64 Russian tanks moved into Ukraine from Russia and now are in the hands of the rebels.

About 100 soldiers emerged triumphant from the previously rebel-occupied buildings in Mariupol, shouting the name of their battalion, Azov, and singing the Ukrainian national anthem. They also destroyed an armored vehicle and a heavy truck used by the separatists, leaving the vehicles scorched and riddled with large-caliber bullet holes.
