Baku, Azerbaijan – According to the head of state, there are “about five to six” Turkish F-16 jets in Azerbaijan. Turkey’s F-16 fighter jets stationed in Azerbaijan could be used in case of external aggression against Azerbaijan, President Ilham Aliyev said Monday.

“I am often asked: what do Turkish F-16s do in our country? I’m tired of answering that. If you have satellites, then take a look, make sure that [the planes] are on the ground, not in the sky. They have arrived to take part in military drills and stayed here after the war started. Our Turkish brothers have left them here as a moral support for us. But should an aggression take place against us from the outside, then they [the aggressor] will see these F-16,” Aliyev said in a televised address to the nation.
