On Sept. 9, one day after two H-6G maritime strike aircraft had been intercepted by the Japan Air Self Defense Force F-15 scrambled from Naha while flying in international airspace between the Miyako and Okinawa islands, an unknown Chinese UAV (unmanned aerial vehicle) was intercepted near the contested Senkaku islands.
Based on the image released by the Japan MoD, the UAV seems to be a Wing Loong (Pterodactyl), a drone based on the U.S. MQ-1 Predator.
Update: as suggested by several readers the drone is actually a BZK-005 more than a Pterodactyl.
