As reported by Censor.NET, this was announced by the ATO press center on Facebook.
According to the HQ information, in this way the mercenaries are trying to provoke Ukrainian troops to fire in order to subsequently blame Ukraine of the Minsk agreements violation, as well as explain why they have not withdrawn weapons from the front line as stipulated by the peace agreements.
"Starting from 6 p.m. yesterday and until 6 a.m. this morning, terrorists at the Donetsk direction were firing with mortars, grenade launchers, large-caliber machine guns, and small arms against Krasnohorivka, Pisky, Troitske, Avdiivka, and Marinka. At the Artemivsk direction they used small arms to fire at Maiorsk and Zaitseve. At the Mariupol direction [they shelled] Bohdanivka and Shyrokyne areas, at the Luhansk direction - Horikhove," the message reads.
In total, the pro-Russian terrorists opened provocative fire 30 times against the Ukrainian military.
