Israeli PM Benjamin Netanyahu has given a statement on the Flydubai flight incident.
He says "the pilot who carried out the stabbing was arrested and is currently being questioned by the Saudi authorities".
The plane was travelling from Dubai to Tel Aviv when it plummeted 17,000ft (5,200m) in less than two minutes, before being diverted to Saudi Arabia.
Netanyahu says the pilot who launched the attack has been arrested and is being questioned by Saudi authorities.
Here is more from the Israeli prime minister's statement:
During the flight, as they were approaching Israel, one of the pilots stabbed the other pilot and, apparently, tried to crash the plane with its passengers on board.
I spoke with one of the Israeli passengers. He told me that the plane went into a spin and began to descend. He told me that, somehow, he managed to break into the cockpit with one of the crew members and, together, they overpowered the pilot who had carried out the stabbing while he was attempting to sabotage the aircraft's systems.
Another air crew who was on the plane entered the cockpit and managed to stabilise the aircraft.
I salute these heroes who demonstrated extraordinary resourcefulness and courage. They saved many lives and prevented a major disaster.
The plane landed safely at Tabuk Airport in Saudi Arabia. All the passengers are now out of danger.
The pilot who carried out the stabbing was arrested and is currently being questioned by the Saudi authorities.
The diverted Israel-bound Flydubai airplane is one of the airline's 10 daily flight from Dubai to Tel Aviv.
The airline's first flights depart Dubai at 05:15 local time (02:00 BST), with the last one setting off at 19:15.
Ten flights also depart from Tel Aviv headed to Dubai each day, with the last one leaving Israel at 22:50 local time (20:50 BST).
The majority of direct flights on this route are chartered by Flydubai and scheduled to take three hours and 25 minutes. Other airlines, such as Arkia and Israir, also have flights on the route but they are not as frequent.
Israel and the United Arab Emirates (UAE) established diplomatic relations in 2020 under a US-brokered deal known as the Abraham Accords. The deal resulted in the normalisation of relations between Israel and the UAE. Saudi Arabian airspace was blocked to Israeli air traffic before the deal.
