Who is behind the weapon and who brought it down.. 7 questions revealing details of the attempted hijacking of a "Fly Dubai" plane

- While investigators across the Middle East continue to probe the alleged kidnapping attempt involving Fly Dubai flight FZ1073, which was en route from Dubai International Airport to Tel Aviv, we take a look here at what we know - and what we do not know - about this incident. Investigators are still trying to determine the motive behind the attack by the unidentified Omani suspect on his fellow pilot.

The UAE is investigating whether the violence is linked to "terrorist activity." Israeli Prime Minister Benjamin Netanyahu told Ofok News that it is too early to determine if Iran is involved, before later stating to Fox News that the alleged attacker "had undergone a process of indoctrination in extremist Islamic ideas."

Passengers on the plane, along with various officials, described the pilot as having been "stabbed." While investigators have not yet disclosed any details regarding the weapon used, Netanyahu stated that the pilot was stabbed or struck with an axe.

How could a knife or axe have been brought onto the plane? Netanyahu suggested that the co-pilot may not have been required to pass through a metal detector, and thus "could have carried a knife or axe," or perhaps used an axe that was already on board the aircraft.

Under aviation safety regulations, an emergency axe is considered mandatory equipment on most passenger planes and is used in emergencies for firefighting, breaking doors and windows, and removing obstacles. Saudi authorities have detained the alleged attacker and subjected him to interrogation.

His identity has not been publicly revealed, other than that he is an Omani citizen. Netanyahu stated that he will be transferred to the UAE for questioning, with Israel participating in the investigation.

Captain Smit Matchar, the injured Indian pilot, underwent surgery on Wednesday, and his condition is stable, according to a local political official in his hometown. Flydubai stated that the aircraft was successfully secured by the Flydubai crew on duty who were on board the flight, as they diverted its course and landed safely at Tabuk Airport.

Israel applies some of the strictest aviation security protocols in the world. An Israeli security official told Afaq News that the Israeli internal security service "Shabak" is supposed to examine all employees of airlines traveling to Israel from the UAE.
