The separatists launched 41 attacks on the government troops in the past day, army operation press centre reported on Saturday morning. They keep using heavy artillery, mortars, grenade launchers, rocket-propelled grenades, and small arms. Most attacks concentrate around the strategic government-controlled seaport Mariupol near the border with Russia, as well as the separatist-held city of Donetsk. Two Ukrainian soldiers were wounded in the hostilities over the past day, military spokesman Oleksandr Motuzianyk told a press briefing in Kyiv on Tuesday noon.
