A FlyDubai flight carrying more than 180 Israeli passengers from Dubai to Tel Aviv was diverted Wednesday morning amid a suspected hijacking incident, according to initial reports approved for publication by Israel’s military censor.

Flight FZ1073 initially transmitted squawk code 7700, the international signal for a general emergency, before reportedly transmitting 7500, the code used to indicate an aircraft hijacking. The aircraft subsequently changed course while over Saudi Arabia. Flight-tracking data independently confirmed that the aircraft declared an emergency and turned around over Saudi Arabia.

Initial Israeli reports said the aircraft was being diverted to Saudi Arabia as authorities investigated a possible hijacking.

Israeli fighter jets were scrambled toward the aircraft as the incident unfolded. The flight also disappeared from public tracking on FlightRadar24.

The circumstances aboard the aircraft remain unclear, and there has been no official confirmation that a hijacking actually occurred.

This is a developing story.
