All flights in and out of Tripoli International Airport were cancelled on Wednesday until further notice because of a sand storm known as the ghibli.
Ibrahim Belhaj, deputy director of Tripoli International Airport, told the Libya Herald that 21 flights -- 13 international and eight domestic -- were cancelled since 10 am; several flights were also diverted to other airports because of the poor visibility.
Large numbers of passengers were stranded at the airport as a result and were waiting for the ghibli to lift, which could take take one or two more days.
The airport was supposed to have been re-equiped with with an Instrument Landing System (ILS) for use in low visibility, but this has not yet been done.
