Tunis Airport

This is Tunis International Airport, it is a small airport. When we fly from Dubai to Tripoli (Libya), we will have to stop here for about 2 hours, so total hours from Dubai to Tripoli become 9 hours. We are not allowed get down from the plane, just wait inside the plane. This is the Control Tower in the airport, it is a small one also. Not many airplanes land in this airport a day. All are from the near by countries. But, when we go back to Dubai, we don't need to stop in this airport, as such, it will take only 7 hours to reach Dubai. I heard from one of the locals in Tripoli, they told us that because there was an misunderstanding between the Corinthia Hotel in Tripoli (the only 5 stars hotel in Tripoli) and Emirates Airline staff, that's why Emirates staff decided to stay in hotels in Tunis then in Tripoli. As such, the flight have to stop in Tunis. I don't how true is this.
