Ukraine says one of its soldiers has been killed and three wounded in clashes in the country's east.
The Defense Ministry said on March 12 that Russia-backed separatists violated a frequently breached cease-fire several times during the previous 24 hours by firing machine guns.
The separatists claimed Ukrainian government forces violated the cease-fire several times using mortars and machine guns.
Since April 2014, more than 10,300 people have been killed by fighting between Ukrainian government forces and Russia-backed separatists who control parts of the eastern regions of Donetsk and Luhansk.
Cease-fire deals announced as part of the Minsk accords -- September 2014 and February 2015 pacts aimed at resolving the conflict -- have failed to hold.
Kyiv said earlier a new cease-fire agreement that took effect on March 5 was violated by the separatists almost immediately.
