The separatists' attacks included the use of heavy arms. They shelled the Ukrainian forces with mortars, grenade launchers, heavy machine guns, and small arms. Most attacks are reported near the strategic government-controlled seaport Mariupol near the border with Russia, and in the vicinity of separatist-held Donetsk. More attacks are reported around the militant-controlled Luhansk. One Ukrainian soldier was wounded in the hostilities in the past 24 hours, military spokesman Oleksandr Motuzianyk told a press briefing in Kyiv Wednesday noon.
