A woman died and at least four people were wounded when fighting flared again in eastern Ukraine overnight into Sunday, questioning a cease-fire struck less than two days earlier between Ukrainian government forces and pro-Russian separatists, according to The Associated Press.
Shelling resumed near the port of Mariupol on the Sea of Azov late on Saturday, just hours after Russian President Vladimir Putin and Ukrainian counterpart Petro Poroshenko had agreed in a phone call that the truce was holding, the AP reported.
Rebel fighters danced and drank in the village on Sunday morning in celebration after what they said was a successful assault on a Ukrainian military encampment in the area, according to the AP. The fighter, who gave only his pseudonym Khokhol, said the truce was not being respected by either side.
"There was mortar shelling around 20 minutes ago here in Spartak," he said, the AP reported. "There is no cease-fire for anyone."
The cease-fire is part of a peace plan intended to end a five-month conflict that has killed nearly 3,000 people and caused the sharpest confrontation between Russia and the West since the Cold War, the AP reported.
Fighting also broke out early on Sunday on the northern outskirts of rebel-held Donetsk, the region's industrial hub, according to the AP.
In a new report on the conflict, Amnesty International accused both the rebels and Ukrainian militia of war crimes and it published satellite images it said showed a build-up of Russian armor and artillery in eastern Ukraine, the AP reported.
"Our evidence shows that Russia is fuelling the conflict, both through direct interference and by supporting the separatists in the east. Russia must stop the steady flow of weapons and other support to an insurgent force heavily implicated in gross human rights violations," Amnesty Secretary-General Salil Shetty said in a statement, according to the AP.
Moscow denies dispatching forces or arming the rebels despite what NATO says is overwhelming evidence to the contrary, the AP reported.
