Hutsuliak said that at 00:45 Kyiv time on August 6, the enemy opened fire from cannons installed on infantry fighting vehicles, grenade launchers, heavy machine guns and rifles, and the shelling of Ukrainian positions near the village of Bohdanivka in Donetsk region lasted for almost an hour.

At 10:20 Kyiv time on the same day, the Russian invaders started firing from a hand-held anti-tank grenade launcher on the positions of the Joint Forces near the village of Pavlopil.

"We express our sincere condolences to the relatives and friends of our military, as well as their fellow soldiers," Hutsuliak added.

The so-called "harvest" ceasefire started at midnight on July 21 in keeping with agreements reached by the Trilateral Contact Group in Minsk on July 17. It has become the 20th truce agreed since the beginning of war in Donbas.

The JFO HQ says that the Armed Forces of Ukraine are abiding by the agreements but will fire back in response to enemy attacks.
