"One soldier was killed and another one was injured in a landmine blast near the [militant-held] town of Horlivka," Motuzianyk said.

The ATO press center in turn reported that there was no complete ceasefire in the past 24 hours in the ATO zone. The truce from midnight to 20:00 local time on Saturday collapsed in three attacks on Ukrainian positions in the Artemivsk sector at the end of the day.

At about 20:00, 22:00 and 24:00 on Saturday, Russian-backed militants used small arms and heavy machine guns to shell positions of the Ukrainian military in the village of Lozove. The Ukrainian troops were also under sniper fire.

"What is more, at 20:50 and 23:10 local time, militants in the temporarily occupied territory near the village of Troyitske started using automatic grenade launchers to shell in the direction of the contact line, trying to provoke an armed standoff with the ATO forces," the ATO press center said.

After midnight on September 27, the Russian-backed terrorists again fired on the Ukrainian strongholds in Lozove.
