Thirty-five attacks were observed in the vicinity of separatist-controlled Donetsk, and 21 in the area near the strategic government-held port city Mariupol; the gunfire intensity reduced a lot after midnight, the report said. Shelling the villages around these cities, the separatists keep using banned heavy arms that were to be withdrawn under Minsk agreements on settling the conflict. They use mortars, grenade launchers, large-calibre machineguns, as well as small arms. An air defence launcher was used near the village of Krasnohorivka. In some cases, our soldiers fired grenade launchers and small arms," said the report by the army operation headquarters.
