Israeli Prime Minister Benjamin Netanyahu publicly compared the Flydubai cockpit stabbing to the September 11 attacks [2][41] and pledged that Israel would trace the incident to its origin, including whether Iran was involved [1][6]. The remarks came after a co-pilot stabbed Captain Smit Machchhar aboard flight FZ1073 from Dubai to Tel Aviv, forcing an emergency landing in Tabuk, Saudi Arabia [9][13]. The Boeing 737 Max 8 plunged by differing accounts roughly 14,000 to 17,000 feet — over a span estimated at between about 30 seconds and two minutes — before passengers and off-duty crew subdued the attacker [17][24][13].

Netanyahu told Fox News the co-pilot, identified as an Omani national, had undergone "Islamist radical indoctrination" and was suicidal [6]. Israeli Defense Minister Israel Katz described the event as "an attempted jihadist terror attack" [9][13]. Israel's foreign ministry briefed diplomats that the incident was "an attempted terrorist attack against Israelis, the United Arab Emirates, and the Abraham Accords" [13]. An unnamed Israeli official said the co-pilot's social media accounts showed jihadist radicalization and discussions of killing Jews [35]. Netanyahu said a vetting loophole had allowed the pilot to fly to Israel and that Israel was addressing it with Emirati cooperation [6][35].

Flydubai stated that "the underlying reasons and motives behind this event are unknown and remain subject to a formal investigation" and urged all parties to "refrain from premature speculation" [9]. The airline confirmed a cockpit altercation, said the aircraft landed safely at Tabuk with all passengers accounted for, and suspended all flights to and from Israel [10][22]. The UAE chief prosecutor, Hamad Saif al-Shamsi, announced an investigation to determine whether the incident was linked to terrorist activity or prior planning [25][29]. Israeli envoy to the UAE Yossi Shelley cautioned that no motive had been determined [30][43], and Israeli security officials said the initial assessment was that the co-pilot likely acted alone with no sign of Tehran's involvement [43]. NBC News reported no indication of Iranian direction, citing US and Israeli officials [33].

US President Donald Trump said Iran would be "hit very hard" if it was deemed to have been involved [6]. Trump told reporters the co-pilot was "perhaps a terrorist or perhaps a whack-job" [9][13], and separately suggested Iran may be connected "based on what I'm hearing" [26]. Netanyahu said it was "too early" to confirm Iranian involvement but that Israel would reach "the origin" of the attack [1][42]. Israeli media raised the prospect of retaliation: Maariv wrote that if a state was found behind the plot it could amount to a declaration of war, and Kan News reported a standing Israeli Air Force plan, prepared after 9/11, for responding to terror attacks using civilian passenger aircraft [14].

Passengers described a sudden descent after the cockpit altercation. Passenger Almog Itali said the plunging aircraft felt like a "rollercoaster" [28]. A passenger told Le Monde of a sudden loss of electrical systems followed by screams of "knife attack, knife attack, blood, blood" [39]. Yaniv Hayun, an Israeli plumber, said he entered the cockpit, put the attacker in a chokehold, and pulled the control column back [13][30]. Dr. Shota Musayev bound the attacker with headphone cords and gave Machchhar first aid [20][29]. Netanyahu, Indian Prime Minister Narendra Modi, and Israeli President Isaac Herzog praised the captain and passengers as heroes who prevented a 9/11-scale disaster [6][15][29]. Modi posted on X that Machchhar "showed the world the highest form of courage" and "prevented another 9/11 like attack from happening" [24].

Aviation-security experts noted that post-9/11 protections are designed to keep threats out of the cockpit, not to address insider threats. Jeff Price, a professor of aviation security at Metropolitan State University of Denver, said "everything we did was to try and prevent access to the flight deck, which doesn't do a whole lot of good when the problem is coming from inside the house" [24]. Aviation safety lecturer Oleksandra Molloy said the presence of a weapon on board was "quite concerning" and could lead to stricter security checks for crew and pilots [8]. Israeli PMO spokesperson Doron Spielman said Israel would identify every pilot flying into the country and conduct security checks [25][37]. Israeli Transportation Minister Miri Regev urged Netanyahu to ground Flydubai flights and prioritize Israeli carriers [5].

Jurisdiction over the suspect and the investigation is contested among Saudi Arabia, the UAE and Oman, with Israel seeking a role. The UAE asserts jurisdiction as the state of registry [1][29]. Saudi Arabia held the suspect and transferred him, along with the captain, to Abu Dhabi after medical clearance [6][29]. Oman holds the suspect's nationality, confirmed by an Omani official to CBS News [34]. Netanyahu said UAE President Mohamed bin Zayed agreed Israel could join the interrogation [40]. Israeli National Security Minister Itamar Ben Gvir demanded the suspect be extradited to Israel, though no extradition treaties exist with Saudi Arabia, Oman, or the UAE [35]. Mohamed Mahmoud Mehran, a professor of international law, said jurisdiction is split among Saudi Arabia, the UAE, and Oman, and said the Israeli and US political framing must not affect the legal investigation [45].

Opposition figure Yair Lapid cast doubt on any connection between the incident and a pre-election warning Netanyahu had issued the day before, saying a security briefing gave no information about a similar potential incident [13]. Le Monde noted that Netanyahu had warned of possible attacks ahead of the October 27 legislative elections [39]. Al Jazeera reported that Israeli officials were calling the incident a "terror attack" before the airline's investigation was complete [2].

The co-pilot is now in UAE custody, with the UAE prosecutor's investigation underway [29][44]. Flydubai has suspended flights to and from Israel, and Emirates has suspended its codeshare flights with flydubai to and from Tel Aviv [16][22], while El Al announced special rescue flights from Dubai to Tel Aviv [8]. Netanyahu said Israel would know quickly whether Iran was involved [41].
