They shelled the Ukrainian forces with anti-tank grenade launchers, mortars, heavy machine guns, and small arms. Most attacks are reported near the strategic government-controlled seaport Mariupol close to 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 on Thursday.
