Fierce clashes between police and protesters, some including gunfire, shattered a brief truce in Ukraine's besieged capital Thursday, killing numerous people. The deaths came in a new eruption of violence just hours after the country's embattled president and the opposition leaders demanding his resignation called for a truce and negotiations to try to resolve Ukraine's political crisis.
