A co-pilot on a Flydubai flight from Dubai to Tel Aviv reportedly attacked the captain with an axe. The weapon used was identified as a "crash ax," a standard piece of equipment found on many aircraft.
Officials in the United Arab Emirates have characterized the incident as a "terrorist act." Passengers on board the flight are credited with intervening to prevent the co-pilot from crashing the aircraft.
Reports indicate passengers stated they were asked to free the co-pilot, but only to law enforcement. This is a developing story and will be updated as details emerge.
