One Ukrainian soldier was killed in a road accident and six soldiers were wounded in hostilities in the Anti-Terrorist Operation (ATO) zone in Donbas in the last day, presidential administration spokesman for ATO issues Oleksandr Motuzianyk said.

"No one was killed in combat in the past 24 hours, but there are six wounded. Another soldier died in a road accident," he said in Kyiv on Tuesday.

Motuzianyk also briefed on the situation in the ATO zone.

In his words, the truce in the Luhansk sector was violated in the region's eastern and western areas – the village of Bolotene in Stanychno-Luhansky district and the town of Popasna.

The enemy again used cannon artillery systems in the Donetsk sector, he said.

"What is more, ATO forces remain under heavy mortar fire, as the occupiers have fired more than 230 mortars in the past 24 hours. This is a record high number since last summer. The main hot spots are the village of Luhanske along the Svitlodarska Duha – a stretch between the militant-controlled town of Horlivka and the town of Svitlodarsk in Donetsk region, as well as the outskirts of the militant-held town of Horlivka (Zaitseve, Leninske) and the town of Avdiyivka," he said.

The Ukrainian military intelligence service reported that militants had deployed a set of Grad multiple-launch rocket systems at the western part of the village of Mineralne.

"A local civilian has been wounded as a result of enemy shelling of Avdiyivka. Hostilities in some sections of the front line have become 24/7, therefore the ATO forces regularly open fire to counter illegal armed groups' aggression," the source said.

The Mariupol sector saw violation of the truce in the towns of Maryinka and Shyrokyne. All the attacks were direct shelling. Ukrainian troops returned fire.
