Ukraine's representatives in the Joint Center on Control and Coordination of issues related to the ceasefire regime and the stabilization of the situation on the line of contact in the Donbas (JCCC) have accused militants of violating the ceasefire agreement that was approved by the Trilateral Contact Group on resolution of the conflict in the Donbas (Ukraine, Russia, and the Organization for Security and Cooperation in Europe) from 10 a.m. on Thursday. This was announced in a statement on the Facebook page of the press center of the ATO headquarters, Ukrainian News Agency reports. "The Ukrainian side in the JCCC hereby states that illegal armed formations in the OPDLO (the non-government-controlled areas of the Donetsk region) began shelling the positions of the Ukrainian Armed Forces at 10 a.m. on April 13 despite the agreement on a regime of complete silence that was reached during a meeting of the Trilateral Contact Group on April 12 this year," the statement said. According to the statement, nine cases of militants firing in the direction of Vodiane, Talakivka, Katerynivka, and Chermalyk with 122-mm caliber artillery, an anti-tank missile system, weapons mounted on infantry fighting vehicles, large-caliber machine guns, and small arms had already been registered as of 9:30 a.m. on April 13. An enemy sniper was operating near Vodiane and Talakivka, the statement said. According to the statement, this proves that ORDLO (the non-government-controlled areas of the Donetsk region) is taking provocative actions to create prerequisites for further aggravation of the conflict in the east of the country. The Ukrainian side firmly holds the position that all sides should comply with all the provisions of the Minsk agreements and strictly fulfill all their obligations, the statement said. In addition, according to the statement, military commanders will decide on the adequate response to the enemy in case of direct threat to the lives and health of Ukrainian soldiers. As Ukrainian News Agency earlier reported, Ukraine's representatives in the Trilateral Contact Group consider it necessary for the Trilateral Contact Group's security subgroup to develop a mechanism for preventing and monitoring violations of the ceasefire regime.
