Ukraine says one of its soldiers has been killed and four wounded in clashes in the country's east.
The Defense Ministry said on May 7 that Russia-backed separatists violated a cease-fire 80 times during the previous 24 hours, firing artillery, machine guns, grenade launchers, and mortars.
Meanwhile, the separatists claimed that Ukrainian government forces violated the cease-fire more than 30 times, using the same type of weapons, and wounding a civilian.
Since April 2014, more than 10,300 people have been killed in fighting between Kyiv's forces and the separatists who control parts of the Donetsk and Luhansk regions.
Cease-fire deals announced as part of the Minsk accords -- September 2014 and February 2015 pacts aimed to resolve the conflict -- have failed to hold.
A new cease-fire agreement was reached in late 2017 and was meant to begin on December 23, but both sides have accused each other of repeated violations since then.
