"The Kremlin-hired militants were shelling along the whole demarcation line, using 82mm mortars and the 120mm-caliber ones, which are banned by the Minsk agreements. In particular, the militants fired from the occupied Donetsk and its outskirts on the towns of Maryinka and Krasnohorivka, the mine of Butivka, and the village of Pisky [near the destroyed Donetsk airport]. In Luhansk region, the villages of Kriakivka, Novotoshkivske, the town of Zolote and the village of Stanytsia Luhanska came under fire. In the direction of Artemivsk, the militants fired mines and grenades on the positions of the Ukrainian army near the villages of Kirove, Leninske and Maiorske. In the south of Donetsk region, the villages of Novotroitske and Hranitne were under enemy mortar fire," the report says.

Since midnight the situation in the ATO zone has remained tense, the press center said. Militants have used banned artillery weapons in five out of ten cases of the violation of the ceasefire.

In particular, they fired 122mm howitzers on the villages of Druzhba and Vrubivka in the direction of Artemivsk, as well as Grad multiple rocket launchers on the town of Zolote.

The press center reported it had information that illegal armed groups were going to boost their subversive activity in Luhansk region.

"According to our data, the invaders are preparing another large-scale provocation, in particular, in the village of Stanytsia Luhanska. We do not rule out that the Kremlin's mercenaries may prepare and implement terrorist attacks during public events," the press center said.
