According to the Ukrainian General Staff, the militants sent more than ten tanks and up to 10,000 people in the direction of the town of Maryinka. The offensive was supported by 2S1 Gvozdika 152-mm self-propelled artillery systems. In other areas, the militants fired on the positions of the Ukrainian army with guns and heavy mortars of calibers that should have been withdrawn from the front line weeks ago under the Minsk peace accords.

It was also reported that the Ukrainian side had to use heavy artillery to fend off the Russian-backed militant attacks.

As reported earlier, Deputy Commander of the Dnipro-1 Battalion Valentyn Manko wrote on his Facebook page that, according to intelligence sources, the militants had deployed a lot of weapons near the village of Baturyne, the town of Maryinka, and the villages of Pisky and Pervomaiske.

He said that if the militants manage to break through the Ukrainian defensive line, there was a risk that Ukrainian forces could be surrounded in the area of Pisky, Karlivka and Avdiyivka.
