Armenia’s move to allow Azerbaijani flights over its airspace is one of the worst possible signals that could be sent to Iran, according to expert on Iran Vardan Voskanyan.

As Panorama.am reported earlier, Azerbaijan Airlines started operating Baku-Nakhichevan-Baku flights through Armenia's airspace on Wednesday.

“Allowing an enemy aircraft to fly over Armenian airspace exactly today and in this particular direction is one of the worst possible signals that could be sent to Iran,” Voskanyan wrote on Facebook.

The move came one day after Iran banned Azerbaijani military planes from flying over the Islamic Republic to Nakhichevan.
