The separatists attacked the Ukrainian positions using mortars, APCs, grenade launchers, air defence guns, large calibre machineguns, and small arms. Most attacks are reported near the strategic government-controlled seaport Mariupol and the separatist-held city of Donetsk. One Ukrainian soldier was killed and three were wounded in the hostilities over the past day, military spokesman Andriy Lysenko told a press briefing in Kyiv on Friday.
