The attack came just two days after an Islamic faction operating in the area launched a barrage of mortar rounds at the airbase severely damaging two planes.
As darkness fell, Russia air defense systems detected "13 unidentified small-size air targets at a significant distance" swarming towards the bases. Ten assault drones were fast approaching the Khmeimim air base, and another three were advancing towards the naval base. All attack drones had payloads of what appears to be mortar rounds.
As the drones approached both bases, Russia unleashed the Pantsir-S anti-aircraft missile and Electronic Warfare Units. Seven UAVs were destroyed by the Pantsir-S anti-aircraft missile system, and another six UAVs were hacked with radio equipment. Three of the UAVs landed in a safe area just outside the base, but the others exploded on various landing attempts. The Defense Ministry notes that the defense systems eliminated all threats with no casualties or damages.
