The situation was most tense near the militant-held city of Donetsk and the separatist-controlled town of Horlivka.
"The enemy fired rocket-propelled grenades and heavy machine guns on our positions in the villages of Pisky [near the ruined Donetsk airport', Opytne, the town of Avdiyivka and Butivka coal mine," the report says.
The town of Maryinka was attacked seven times with the use of small arms and rocket-propelled grenades.
"The occupiers used mortars, rocket-propelled grenades and heavy machine guns near Horlivka. They fired grenade launchers of various systems on our fortified positons in the villages of Troyitske and Novhorodske, as well as 82mm and 120mm mortars on the Ukrainian positions in the villages of Mayorsk and Zaitseve," the press center said.
The militants also fired mortars on ATO forces in the town of Krasnohorivka.
"The Russian-backed mercenaries fired grenade launchers and small arms on our fortified positions near the villages of Kodema, Starohnativka and Novohryhorivka," the report reads.
