Israeli Prime Minister Benjamin Netanyahu has stated that investigations suggest the man who attacked a co-pilot on a Flydubai flight from Dubai to Tel Aviv had undergone Islamist radical indoctrination. The incident saw the Flydubai plane plunge more than 17,000ft (5,200m) during its journey on Wednesday before passengers and crew subdued the attacker.

Netanyahu told Fox News that the attacker, identified as an Omani national, was likely intending to bring the plane down. The dramatic descent occurred two hours into the flight, prompting a swift response from those on board who overpowered the assailant and regained control of the aircraft to ensure a safe landing.

Investigations are underway in the United Arab Emirates to determine if the incident has links to any terrorist activity, according to the UAE state news agency. Meanwhile, Saudi Arabia's Interior Ministry confirmed that the pilot and co-pilot, both cleared by medical teams, were returned to the UAE on Thursday morning following the emergency landing in Saudi territory.

UAE officials have asserted jurisdiction over the incident, citing the aircraft's registration and flag. Netanyahu also shared that once subdued, the attacker repeatedly urged the aircrew to "kill me, kill me," which he interpreted as a clear indication of suicidal intent, rather than a point of question.

Adding to the context of the attacker's background, Netanyahu alluded to "Islamist tendencies" and "radicalisation found in his background." He cautioned against drawing firm conclusions about the motive at this early stage, however.

Both U.S. President Donald Trump and UAE officials have publicly suggested Iran's potential involvement, though without definitive accusations. Trump warned of severe repercussions for Iran if its role in the attack is confirmed.

Questions have arisen regarding how an Omani pilot, from a country without diplomatic ties with Israel, was permitted to fly the plane. Netanyahu acknowledged a "loophole" in the system, which is being addressed with the cooperation of the Emirati government to prevent future occurrences.

Oman does not officially recognize Israel, unlike the UAE. When asked earlier about potential Iranian involvement, Netanyahu stated it was "too early to say." The incident has highlighted security vulnerabilities and prompted international scrutiny, with authorities in multiple nations collaborating on the investigation.
