Heavy fighting threatens Ukraine ceasefire
Gunfire and heavy shelling rocked a key frontline city in eastern Ukraine overnight, raising fears today that a tenuous truce between government and rebel forces had already collapsed.
Artillery fire was also heard today, near the airport of the main rebel-held city of Donetsk.
Pro-Russian fighters had bombarded a government-held checkpoint on the eastern edge of the strategic port of Mari-upol last night, triggering a fire-fight that sent local residents into panic.
The violence erupted just hours after a phone call between Ukraine's President Petro Poroshenko and his Russian counterpart Vladimir Putin, who agreed that the ceasefire was "generally being observed".
