Over the past 24 hours, Ukrainian armed forces violated the Complex of Additional Measures for Ceasefire Control four times, committing three firing provocations, including the use of mortars, spokesman for the DPR PMD Oleg Nikitin reported at the briefing on December 23. At the Gorlovka front, militants from the 503rd Marine Battalion of the 35th Brigade of the AFU, in violation of the Clause 2 of the Additional Measures, opened fire from positions near the Yuzhnaya mine in Dzerzhinsk with RPG, AGS and small arms in the direction of the village of Mine 6-7 in Gorlovka, firing a total of 27 grenades. At the Donetsk front, militants from the 1st mechanized battalion of the 72nd Brigade of the AFU attacked the Mikhailovka area with 120mm mortars from positions near Verkhnetoretskoye (north). In addition, our observers registered engineer work at positions of the 37th Battalion of the 56th Brigade of the AFU near Opytnoye. At the Mariupol front, militants from the Marine Battalion of the 36th Brigade of the AFU fired eight 120mm shells at Leninskoye from positions near Vodyanoye. Our defenders did not react to the provocations of the enemy, continue monitoring, strictly observing the current ceasefire, and are ready to adequately respond to the actions of the enemy. In addition, the AFU continue to use electronic warfare means to prevent OSCE SMM drones from detecting prohibited weapons and new positions of their units, built up in violation of the Complex of Additional Measures for Ceasefire Control.
