Shelling has raged on after nightfall in Eastern Ukraine, with both Government Troops and Pro-Russian Rebels reporting new casualties.
Ukrainian Officials say two Civilians were killed when the separatists fired on the government-held frontline town of Avdiivka.
The separatists say two civilians died as the government shelled the Rebel stronghold of Donetsk.
At least 15 people have been confirmed killed in the worst fighting for weeks.
A number of people have been injured since the clashes intensified over the weekend.
There are fears that the actual death toll could be much higher.
Ukraine accuses Russia of launching an offensive, while Moscow says Kiev is seeking to push back the separatists from their positions in the Donetsk and Luhansk Regions.
The two countries again traded accusations during an urgent UN Security Council session to discuss the conflict which has claimed the lives of more than 9,700 people since 2014.
