The separatists attacked the Ukrainian positions using mortars, grenade launchers, 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. No casualties among government troops were reported over the past day, military spokesman Oleksandr Motuzianyk told a press briefing on Friday. However, he said one civilian was injured as a result of a mine explosion on Thursday.
