Newly released images of the three drones attacking the military base Hmeimim and Tartus show that the three handmade UAVs are still intact, made from foam, pressure board, metal wire, covered with tape and blue polyethylene plastic.
In addition, a photo shows the debris from three other UAVs arranged in separate piles.
The Russian Defense Ministry has stressed in previous statements that designs used by rebels could only come from a country with advanced technology, and warned of the risk of such attacks in any country in the world.
However, the Pentagon said such devices could be easily found in skyrocketing.
The photos were released after the Russian Defense Ministry's report on January 8 on an attack on a Russian military facility in Syria on January 6. Ten drones targeted the Hymymim air force and three were sent to the Tartus naval base. As a result, 3 UAVs were controlled by Russia, 3 others exploded after falling and 7 others were shot down.
According to Krasnaya Zvezda, the official release of the Russian Defense Ministry, drones attacking the Hmeimim air base departed from the southwest of the area where Idlib conflict has escalated in Syria and were controlled by the moderate opposition.
