One Ukrainian soldier was killed, another three were wounded in the Anti-Terrorist Operation (ATO) zone in eastern Ukraine in the last day, spokesperson for the Ukrainian Presidential Administration Andriy Lysenko said.

"One Ukrainian soldier was killed, another three were wounded. The soldier died amid the shelling of the village of Zaitseve. Two of the injured suffered wounds during the mortar shelling of Mayorsk, and the third one was injured when Maryinka came under mortar fire," he said at a briefing in Kyiv on Friday.

Lysenko reported about escalation of the situation in the ATO zone: militants attacked the Ukrainian positions 81 times.

"The enemy used heavy weapons 12 times. The situation was calm only in the Luhansk sector – not a single shot was fired there towards the Ukrainian positions," he said.

Combats stretched along the entire front line in the Donetsk sector, the most difficult situation remains in Zaitseve and Mayorsk where the ATO forces were attacked by mortars of different caliber.
