Heavy fighting in E. Ukraine as ceasefire ends

Heavy fighting resumed in eastern Ukraine early Tuesday, including artillery shelling around the rebel-controlled city of Slavyansk, shortly after President Petro Poroshenko declared an end to a 10-day cease-fire and ordered government forces to renew their effort to crush the pro-Russian separatist insurrection.

Friday, European leaders issued an ultimatum to Russia, to do more to end rebel violence in eastern Ukraine or face more sanctions.
