Gunfire has broken out in the center of a major city in eastern Ukraine as gunmen appear to be trying to take control of the regional police headquarters. The shooting broke out Tuesday afternoon in Donetsk, the capital of one of the two regions that pro-Russian insurgents have declared independent. An Associated Press journalist saw some blood on the streets but no wounded people. On Monday, Ukrainian President Petro Poroshenko announced the end to a unilateral 10-day cease-fire that he had called to try to induce rebels into talks and to lay down their weapons.
