Reports are still emerging about what happened on board the Flydubai plane. Here is what witnesses and anonymous officials have said so far.

'They think they are going': There were panicked scenes as the plane plunged 17,000 feet - the mother of one passenger reports her saying "all the people, they scream, they think they are going"

'One pilot stabbed the other': Unnamed officials tell Israeli media that one pilot attacked the other with a knife, seemingly to "either hijack the plane... or crash it" - although it's important to state the motive has not been confirmed, and we are yet to get official statements

'Tied down': An Israeli passenger on board tells journalists the crew asked for help from passengers to tackle the attacker and tie him down

'Covered in blood': Witnesses have described violent scenes - one said "there are people here with shirts covered in blood"

'Take control': Two pilots who were at the back of the plane came forward to help land it, one passenger says: "I shouted at them to run and take control of the plane"

The company that owns Tabuk airport in Saudi Arabia - where the plane was diverted - has just put out a statement.

It says both the captain and first officer on the Flydubai plane sustained injuries and were taken to the hospital. It does not state the cause of the injuries.

The airport's air traffic control centre received a distress call from the Flydubai plane at 08:44 local time, the statement says, during which the plane requested an emergency landing

The aircaft landed safely around an hour after, the statement adds.

We're getting reports that a recovery flight is on its way to Tabuk, Saudi Arabia, to pick up passengers from the diverted Israel-bound flight.

According to Flightradar24, a separate Flydubai flight (FZ8455) set off from Dubai just before 12:56 local time (09:56 BST) and is due to land in Tabuk at 14:41 local time (12:41 BST).

The flight tracking company says that once the airplane lands in Tabuk, it will take passengers to Tel Aviv, their original destination.

We can now bring you more from Yasmin Abukasis, who has been speaking to journalists from Israel's Ben Gurion Airport, where the plane was due to land.

Yasmin says her daughter, who was on the flight from Dubai to Tel Aviv, phoned her to say she heard screaming on the plane as a pilot called for help.

"The plane start to lose control. So all the people, they scream, they think they are going," Yasmin tells AP news agency.

Speaking to Reuters, Yasmin says two other pilots took control of the plane as other passengers ran towards a man who had a knife.

The flight bound for Tel Aviv dropped extremely rapidly over Saudi Arabia just over two hours after take-off from Dubai, flight-tracking data from Flightradar24 examined by BBC Verify shows.

Just before 05:21 UTC (06:21 BST; 08:21 local time) the plane was cruising at a recorded altitude of 34,000 feet (10,400m).

In less than two minutes it had descended more than 17,000 feet (5,200m).

An emergency signal was issued from the plane about 10 minutes later and the available data shows significant ongoing fluctuations in altitude throughout the rest of the flight to Tabuk airport in Saudi Arabia.

In an interview with Israeli newspaper Israel Hayom, external, a female passenger describes the "very stressful" moment people on board realised the plane was rapidly descending.

"We understood the pilots lost control," she says, recounting terrified screams from passengers.

She tells the newspaper that one pilot suffered serious stab wounds before the attacker could be dragged off him.

"There are people here with shirts covered in blood," she says, adding: "Now we are fine and want to return home."

Emergency signal sounded for seven minutes before flight changed directionpublished at 10:28 BST

Flight FZ103 from Dubai to Tel Aviv issued an emergency signal for around seven minutes, shortly after an abrupt change of direction and descent over Saudi Arabia, according to data from Flightradar24.

The flight took off at 03:05 UTC (04:05 BST), after a 20-minute delay.

The emergency "squawk" code 7700, declaring a "general emergency" was issued at around 05:31 UTC.

Flightradar24 have since said on X that another emergency signal - 7500, declaring "unlawful interference" - was issued at 05:38, although this is not visible on their website.

The flight briefly entered Jordanian airspace at 05:40 before looping back into Saudi airspace six minutes later.

It began descending again at 06:11 on an apparent course towards Tabuk, Saudi Arabia. Location data became temporarily unavailable shortly thereafter, until 06:58, when it re-emerged at Tabuk airport.

We're now getting testimony from passengers, via Reuters.

Yasmin Abukasis tells the news agency that her daughter Miriam was on the flight and that she heard screaming.

Her daughter said a man holding a knife had forced one of the pilots onto the floor, and that there was blood everywhere.

Flydubai confirms its flight "experienced an incident" but says "all passengers are safe and accounted for".

"Flydubai can confirm that flight FZ 1073 operating from Dubai International (DXB) to Ben Gurion International Airport (TLV) on 30 September experienced an incident while en route," a statement says.

"The aircraft has landed safely in Tabuk Airport (TUU) and all passengers are safe and accounted for. The safety and wellbeing of our passengers and crew remain our highest priority.

"Our teams are working closely with the relevant authorities. Further updates will be issued as additional confirmed details become available."

It’s reported the alarm was caused after a 'fight' between the pilot and the co-pilot.

An Israeli passenger on board has told journalists the crew asked for help and that passengers then helped tackle one of the pilots and tie him down.

In a statement, the Israeli Prime Minister Benjamin Netanyahu said the situation was under control and that efforts were underway to return the Israeli passengers home from Saudi Arabia.

A flight from Dubai to Tel Aviv was diverted to Saudi Arabia after a "fight" between the pilots, Israeli officials have told local media.

The Flydubai plane - which took off from Dubai International Airport early on Wednesday - signalled an emergency code two hours into the journey, flight tracking website Flightradar24 says.

Minutes later it switched to a code used to report a hijacking, but was later turned back to the general emergency signal.

The emergency signal is thought to have been issued following an "altercation" between the pilot and co-pilot, local media reports, citing Israeli defence officials.

Flight FZ1073 - carrying about 150 people, most of whom are Israeli - was due to land at Ben-Gurion Airport but instead landed at Tabuk Airport in north-eastern Saudi Arabia.

This is a developing story - we'll have more details soon.
