An Iranian cargo plane was forced to land in Diyarbakir airport in Turkey on Satuday to undergo an inspection to check whether the aircraft was carrying any illicit or military materials on board, AFP quoted security sources as saying on Sunday. The plane had been en route to Syria.
The grounding of the plane followed a similar incident last week in which a Syria-bound Iranian aircraft was forced to land in Diyarbakir, searched and later released.
On Sunday, military fighter planes were on hand in case the civilian Ilyushin aircraft's crew refused to comply with the Turkish authorities order to land.
Inspection of the plane's cargo was reportedly ongoing.
