Austrian Airlines flight OS769 en route from Vienna to Pristina made an emergency landing in Belgrade last night after a loud bang was reported by passengers while the Fokker 100 aircraft was flying over Bosnia and Herzegovina. The jet landed in the Serbian capital late in the evening. Albanian media have reported that many passengers who were solely Kosovan passport holders were unable to disembark the jet, while passengers with Kosovan ID cards were allowed to leave. However, these reports have not been confirmed by Serbian authorities or the airport itself. Under a freedom of movement agreement between Serbia and Kosovo, Kosovan passport holders can transfer through Belgrade Airport onto other flights, although the implementation of the deal remains patchy. According to various unconfirmed reports, travellers who disembarked the aircraft left Belgrade this morning on a Turkish Airlines flight to Istanbul after which they were flown to Pristina. Others are still believed to be in Belgrade. Austrian confirmed its aircraft suffered a technical problem. This is the latest incident to have involved an Austrian Airlines aircraft diverting to Belgrade in the last few weeks. On October 21, a flight from Larnaca to Vienna made an emergency landing in Belgrade due to a cracked windshield, while on October 31 a flight from Vienna to Tel Aviv was forced to land in the Serbian capital due to a technical fault.
