Mercenaries opened unaimed fire to shell Ukrainian troops near Pisky, and the villages of Opytne, Zaitseve, Mayorsk, Luhanske and Myronivsky, provoking them into firing back.
"The combined Russian-separatist forces have still been violating the truce in the ATO zone after recent agreements in Minsk on a full ceasefire and continue mounting armed provocations against our defenders," the HQ said.
