The Ukrainian authorities are concerned about attempts to down UAVs operated by monitors from the OSCE Special Monitoring Mission (SMM) by representatives of the self-proclaimed republics in Donetsk and Luhansk regions and regard this situation as an attempt to hide information about the location of their military equipment that is banned by the Minsk Agreement.

"Alarming are systematic attacks by militant representatives on OSCE SMM drones. This week alone, one drone was shot down and two were damaged. The attacks on drones have an explanation... They collect information about the location of military equipment, and this data shows the non-fulfillment of the Minsk agreements by militant representatives," Darka Olifer, the press secretary of Ukraine's envoy to the Trilateral Contact Group Leonid Kuchma, wrote on Facebook following a group meeting on Wednesday.

It also indicates an increase in the number of ceasefire violations in the occupied territories in Donbas, noting that the attacks are also made from the weapons prohibited by the Minsk agreements.

The issue of control by Ukraine of the Ukrainian-Russian border also remains principal. "Ukraine states: regaining control of this stretch of the state border will contribute to improving the security situation. That is why we insist on discussing this issue in the framework of the Trilateral Contact Group, as well as granting the OSCE SMM access to that stretch of the border," Olifer wrote.
