Their attacks included the use of heavy arms. They shelled the Ukrainian forces mortars, grenade launchers, heavy machine guns, and small arms. Most attacks are reported near separatist-held Donetsk, and in the vicinity of strategic government-controlled seaport Mariupol near the border with Russia. The towns of Avdiyivka and Shyrokyne remain the hotspots of separatists’ attacks. One Ukrainian soldier was wounded in combat in the past day, military spokesman Andriy Lysenko said Wednesday noon.
