Investigators across Saudi Arabia, the UAE and Israel are probing the alleged cockpit attack aboard Flydubai flight FZ1073. While Israel seeks the extradition of the Omani co-pilot, Prime Minister Benjamin Netanyahu has alleged the attacker was radicalised, and US President Donald Trump says a possible Iran link is being examined. Saudi Arabia is leading the initial investigation, with the UAE set to take over as authorities work to establish the motive behind the mid-air terror.
