Militants have violated the ceasefire in Donbas 71 times in the past 24 hours, the press center of Kyiv's army operation in eastern Ukraine has reported.

Ukrainian military checkpoints came under 82mm mortar fire in Zaitseve on the Svitlodarsk arch, while grenade launchers, large-caliber submachine guns, and fighting infantry vehicles were used against Ukrainian army positions in Novhorodske and Mayorsk, the press center said on its Facebook page on Friday.

Different kinds of weapons were fired at Ukrainian Armed Forces positions in Opytne, Pisky, Avdiyivka, and near the Butivka mine, near the city of Donetsk.

Ukrainian soldiers fired back in response to the militants forces' strikes near Maryinka, the press center said.

Militants' units also used an infantry fighting vehicle, and an automatic grenade launcher, against the Ukrainian State Border Guard Service's Maryinka entry and exit checkpoint at 9:10 p.m.

Similar provocations are also possible "at other entry and exit checkpoints, in particular in the Artemivsk area," the Ukrainian Armed Forces headquarters said.
