Leaders to hold talks amid Ukraine clashes

The leaders of Ukraine, Russia, Germany and France are to hold more talks to resolve the conflict in east Ukraine. Germany and France have urged Ukrainian President Petro Poroshenko to extend a ceasefire with pro-Russian separatists - due to end on Monday evening - for a second time. The truce remains under strain, with five Ukrainian soldiers killed in clashes in the east. A Russian state TV cameraman was also shot dead while reporting in Donetsk.
