Turkey's foreign minister, Ahmet Davutoglu, banned all Syrian aircrafts from entering Turkey's airspace, according to the BBC. Davutoglu made his announcement a day after Syria imposed the same ban on Turkey.
The New York Times reported that in his televised comments, Davutoglu "accused Syria of using civilian flights as a cover for transporting military equipment."
Wednesday, Turkey intercepted a plane headed to Demascus, Syria. The plane was forced to land in Ankara, Turkey because Turkish officials believed the plane was transporting weapons from Russia. Both Russia and Syria denied that claim.
The two countries were once allies, but Turkey has supported the rebel effort to take down Bashar al-Assad, Syria's president.
