The Kremlin’s mercenaries often use tanks and mortars, banned by the Minsk Agreements, according to the report. These and other heavy weapons were to be withdrawn to safe distance from the contact line, according to the Minsk deals that stipulated the ceasefire between the warring sides. "The tensest and most dangerous situation was observed in Avdiyivka [north of Donetsk], where the terrorists used mortars and tanks to shell Ukrainian troops over the past day," reads the report. The militants also used grenade launchers, heavy machine guns, and small arms in other parts of Donetsk region. No Ukrainian servicemen were killed or wounded in the area over the past 24 hours, presidential administration spokesman on army operation Andriy Lysenko said at a briefing in Kyiv on Friday.
