A Flydubai flight was headed from Dubai to Tel Aviv on Wednesday when violence broke out in the cockpit. Israeli Prime Minister Benjamin Netanyahu said the co-pilot stabbed the captain in an apparent attempt to crash the plane, which was carrying 174 passengers — mainly Israeli nationals.

The captain, an Indian national, opened the cockpit door, and passengers and crew overpowered the co-pilot, Netanyahu said. An off-duty Flydubai crew took control of the aircraft and made an emergency landing in Tabuk.

The UAE's chief prosecutor said it's looking at the possibility of "terrorist activity or intent" in the alleged attempted hijacking.
