Ukrainian government forces and Russian-backed rebels began withdrawing from a village in the disputed Donbass region on Saturday, one of a series of measures that could pave the way for a summit between Ukraine, Russia, France and Germany. Fighting between Ukrainian forces and Russian-backed fighters in the eastern region has killed more than 13,000 since 2014, with both sides accusing each other of violating a ceasefire that was agreed in the Belarus capital Minsk in 2015. Relations between Ukraine and Russia collapsed following Moscow’s annexation of the Crimean peninsula in 2014, which prompted Western sanctions.
