Ukraine's military has said that two of its soldiers were killed during the previous 24 hours while on a combat mission in the country's eastern Donbas region.
According to a post on Facebook by the Ukrainian Defense Ministry, one of its soldiers was killed as Russia-backed separatists violated a cease-fire deal four times since January 5.
Another soldier was killed inside a military truck that ran over an explosive device near the frontline town of Khutir Vilniy in the eastern Luhansk region.
Another soldier traveling in the vehicle also was seriously wounded, the statement said.
The Ukrainian Defense Ministry said cease-fire violations by separatists also included the firing of 82-millimeter mortar rockets, grenade launchers, heavy machine guns, and different types of firearms at Ukrainian positions in the conflict zone.
Ukrainian forces liberated the town of Khutir Vilniy, also known as Zolote-5, in late September 2018 in the Luhansk region.
Russian-backed forces had often fired on Ukrainian positions from the town, Kyiv had said. It currently has less than 20 civilian residents.
Nearly 14,000 people have been killed in the conflict and 1.5 million more have been displaced.
