"Today, at about 0900, the militants again fired small arms and mortars on the Ukrainian armed forces in the town of Maryinka of Donetsk region," he said.

"During the attack, a sabotage and reconnaissance group of militants tried to approach our positions,” Lysenko said.

“Our soldiers noticed them. Close combat is taking place there. Other details are unknown yet, but we have enough resources to resist the enemy.”

As UNIAN reported earlier, MP and coordinator of the Interior Ministry’s Kyiv-1 special patrol police battalion Yevhen Deidei wrote on his Facebook page on Monday morning that Russian-backed militants again fired tanks and mortars at point-blank range on the Ukrainian armed forces in the town of Maryinka of Donetsk region.

As reported earlier, on the morning on June 3 Russian-backed militants launched a major attack on the positions of Ukrainian troops near the village of Maryinka in Donetsk region, as well as attacking in other areas.

Five Ukrainian soldiers were killed in the fighting (four at Maryinka) and 39 were reported injured.

Due to threat to life of Ukrainian servicemen and civilians in Maryinka, the military command decided to use artillery weapons that had been withdrawn in accordance with the Minsk agreements, which enabled the ATO forces to launch an effective response to the militants’ attack.
