Donbas militants on Sunday attacked Ukrainian positions 50 times, including with 120-millimeter mortars prohibited by the Minsk agreements, according to the press center of the Anti-Terrorist Operation (ATO) headquarters.
"Near Novotroyitske, they used 120-millimeter mortars and anti-tank missile systems," the press center said in an update posted on its Facebook page on Monday morning.
Also, in the Mariupol area, militants fired grenades, machineguns and small arms against Ukrainian troops near Maryinka, Shyrokyne and Taramchuk, the press center said.
In addition, 120- and 82-millimeter mortars were fired 15 times against Ukrainian positions near Avdiyivka. Also, "grenade launchers, large-caliber machineguns and small arms were used [there] repeatedly."
The Ukrainian armed forces on Sunday near Avdiyivka foiled an attempt to storm their positions by returning fire and forcing a sabotage and reconnaissance group to retreat.
In the Donetsk zone, militants shelled Ukrainian positions near the Butivka mine, Luhanske, Pisky, Opytne, and Zaitseve.
Military spokesmen said Ukrainian armed forces returned fire several times.
