"Two drones were flying above sector M (Mariupol) tonight. The first drone appeared at about 2400, and the second one appeared at about 0500. They were fired on at once," the report reads.

They have also used jamming equipment to bring down drones operated by the Organization for Security and Cooperation in Ukraine (OSCE), which was using them to monitor the border area as part of its mandate in eastern Ukraine.
