Saudi Arabia reportedly closed its airspace to Israeli flights on Tuesday morning for unknown reasons, delaying an Israir Airlines flight for five hours at Ben Gurion Airport before departing for Dubai, i24NEWS reports.

Israir flight 661, which was scheduled to take off at 9:00 a.m. local time, was apparently held up because Saudi Arabia refused to grant the necessary permits even though an El Al flight took off for Dubai on Tuesday afternoon with permission to fly through Saudi airspace.
