“Over the course of several days, in three directions at once (Kupyansky, Krasnolimansky, Donetsk), our air defense surveillance systems recorded an increase in air targets,” Marochko said.

He clarified that the work of both manned and unmanned air attack and reconnaissance systems was recorded. 

Earlier it became known that Russian Su-25 attack aircraft attacked units of the Ukrainian Armed Forces in the Donetsk direction, and then performed a “snake” maneuver to prevent the enemy from launching MANPADS missiles.
