The separatists attacked the Ukrainian positions using mortars, grenade launchers, heavy machine guns, and small arms. Most attacks are reported near the separatist-held city of Donetsk and the strategic government-controlled seaport Mariupol near the border with Russia. Two Ukrainian soldiers were killed, and three servicemen were wounded in the hostilities over the past day, military spokesman Andriy Lysenko said at a briefing in Kyiv on Friday.
