An eyewitness video shows passengers evacuating a flight from Warsaw to Paris after reports of a "potential security threat".

"Take-off aborted on the runway. Police, military and sniffer dogs met us. All passengers evacuated to a separate hall," the eyewitness, @bibibebaboy, wrote on X.

As we've just reported, LOT Polish Airlines says the plane was stopped while taxiing and directed to a designated parking stand after reports of a "potential security threat", before undergoing a security screening from authorities.

No hazardous items were found, it says, and passengers will continue their journey on a different aircraft.

The Polish airline, LOT, confirms that two of its flights have been impacted by "security threats" - the Warsaw to Brussels flight, which we reported landed in Brussels, and a Warsaw to Paris flight, which never took off.

It says the Paris flight was "stopped while taxiing and directed to a designated parking stand" before undergoing a security screening in which "no hazardous items were found".

On the flight to Brussels, LOT says the flight crew were "informed of the situation" and carried out an onboard check in which "no suspicious items were identified".

"The aircraft landed at Brussels Airport, where the relevant authorities carried out an additional security inspection. This inspection also confirmed that no hazardous or suspicious items were found," it adds.

More detail now from Aer Lingus, which says its flight from Dublin to Rome, which departed Dublin at 06:40 GMT, was diverted to Normandy "as a safety precaution".

It says the flight "landed safely" and that it is now working to "reaccommodate customers to their final destination as soon as possible".

A statement from the French prime minister’s office says the aircraft was diverted to the Evreux air base, northern France, and landed safely.

"The 151 passengers and six crew members were brought to safety and the bomb disposal teams intervened," the French statement adds.

EU transport chief Apostolos Tzitzikostas says it is "too early" to conclude that reported bomb threats on passenger flights across Europe are "linked".

Tzitzikostas says the EU is "closely monitoring the situation" and is in contract with affected countries.

"It is too early to draw conclusions on whether the reported incidents are linked. National investigations remain ongoing," he says.

As a reminder, there have been at least 15 reported threats today - following at least seven on Tuesday.

Finnish airline Finnair says two of its flights, Helsinki to Rome and the Jettime-operated Helsinki to Vienna, were targeted by "unfounded or hoax bomb threats" on Thursday.

The airline says both flights landed safely at their destinations.

It says authorities in Rome inspected the plane on arrival and "nothing out of the ordinary was found", with an inspection in Vienna "currently under way", with nothing yet found.

"Unfortunately, air traffic is sometimes subject to threats, as we have seen this week, when also other airlines in Europe have faced hoax bomb threats.

"Threats are almost always unfounded," it adds.

The airport authorities in Rome say the hoax threat against two inbound flights received this morning came by email with the subject line: threat notification.

The warnings were signed on behalf of the supposed "Fighters of the Male State" claiming to be targeting a "feminist regime" and wanting to "make our mark on history".

They threatened to "turn the skies red" with explosions.

These details were first reported by Italian media and then confirmed by phone to the BBC by Aeroporti di Roma, which manages both of the city airports.

UK Transport Secretary Heidi Alexander says flights across Europe have been impacted by "malicious hoax threats".

Speaking to broadcasters, Alexander says she is "aware that a small number of flights across Europe have been disrupted" and that there are "established processes for dealing with hoax and malicious threats, and that's what these threats have been".

At least 14 flights have reportedly been affected so far on Thursday, with some diverted. It's the second time this week flights in Europe have been disrupted.

Alexander says the government "take these threats seriously, but we understand these have been malicious hoax threats".

Air travel across Europe has been disrupted after multiple passenger flights reported bomb threats - for the second time this week.

Fighter jets have escorted some planes, with some diverted to alternate airports or military bases.

There have been no reports of explosive found.

In the Czech Republic, police say bomb threats were received on four flights to Prague, with explosives tests "yielding negative results".

Other flights reporting threats include:

• Aegean Thessaloniki to Milan, landed in Milan
• Ryanair Porto to Milan, landed in Milan

• Aer Lingus Dublin to Rome, diverted to Evreux airbase in France
• Finnair Helsinki to Rome, landed in Rome
• Wizz Air Milan to Bucharest, landed in Bucharest
• Wizz Air Milan to Warsaw, diverted to Vienna
• LOT Warsaw to Brussels, landed in Brussels

• Ryanair Copenhagen to Sofia, landed in Sofia
• Ryanair Madrid to Sofia, landed in Sofia
• Ryanair London Stansted to Sofia, diverted to Plovdiv

Wizz Air says its flight from Milan to Warsaw was diverted to Vienna "in accordance with established safety protocols", adding that other airlines were "also experiencing threats".

Aircraft communications (ACARS) from Aer Lingus' Dublin to Rome flight show a "clear account" of the diversion, according to aviation safety expert Marco Chan.

We'll bring you the latest updates as soon as we have them.

Today's disruption follows at least seven flights being searched across Europe on Tuesday after a series of suspected bomb threats.

Two flights were searched after landing in Rome, two in Warsaw, two in Sofia, with one landing in Murcia in Spain - no explosives were found on any of the planes.

Two of these flights took off from the UK - one from Heathrow and one from Manchester.

There is no confirmed link between any of the threats, either from Tuesday or today. But authorities from various countries have been co-operating to assess whether this is a co-ordinated attack.

The UK government described the events as "malicious hoax threats" and said that there are "well-tested processes for dealing with any potential threats".

With bomb threats, the cost to sender is low - but the cost to airlines can be far higherpublished at 11:28 GMT 5 November

An aviation safety expert has told BBC Verify this week’s bomb threats are "most likely a hoax, but the system is right to treat it as real".

Marco Chan, senior lecturer in aviation operations at Kingston University and former Cathay Pacific pilot, says hoax threats are seen by some experts as "possibly part of a pattern of cheap, deniable disruption" to air travel.

He adds that "hoax waves can also come from copycats or a handful of individuals", but that "three days of incidents is too small a sample to separate co-ordination from contagion".

Chan says the "cost to the sender is almost nothing" compared to the significant impact on airlines, airports and air forces.

"That asymmetry is the point of the tactic, whatever the motive."

In this case of this morning’s Aer Lingus flight which was diverted to a military airfield in northern France, Chan says that "diversion, escort, and isolation" at a military site shows the "high cost of false alarms to avoid a single missed attack".

There were no explosives found on the four planes heading to Prague which received threats, a police spokesperson tells CTK news agency.

Earlier, we reported that Czech police were preparing to receive four flights, after threats about an "improvised explosive device".

Budget airline Wizz Air says its flight from Milan Malpensa to Warsaw has been diverted to Vienna after a bomb threat was received during the flight (this flight was on our initial list earlier).

"The diversion was initiated in accordance with established security protocols and procedures, with the safety of passengers and crew as the highest priority," a Wizz Air spokesperson says.

"This incident comes amid a series of similar bomb threats affecting several airlines across Europe in recent days.

"Wizz Air is not the only airline targeted, with other carriers also experiencing threats resulting in flight diversions and security checks."

More now from Bulgaria, where the air force says it successfully carried out an "air policing" mission following bomb threats to three flights.

As we just reported, three Ryanair flights to Sofia, from Copenhagen, Madrid and London Stansted, were reportedly targeted by the suspected bomb threats.

The air force says MiG-29 fighter jets took off from Bulgaria's Graf Ignatievo Air Base at 10:11 local time (08:11 GMT) to "intercept and escort the civilian aircraft".

"One landed at Plovdiv Airport, and the other two at Vasil Levski Airport in Sofia," the air force adds.

In Bulgaria, the Ministry of Transport has confirmed that bomb threats were made against three aircraft arriving in the country.

Two of the aircraft have already landed at Vasil Levski Airport. The flight from Madrid landed at 10:15, while the flight from Copenhagen arrived in Sofia at 10:19. No explosive devices have been found.

The third aircraft, arriving from London Stansted, is yet to land and is expected to arrive at Plovdiv Airport.

All three aircraft are operated by Ryanair.

On-board messages reveal threat was passed on by air traffic controlpublished at 11:01 GMT 5 November

Aer Lingus flight El402, from Dublin to Rome, sent a series of messages between the aircraft and ground stations.

These messages have been interpreted by aviation safety expert Marco Chan, who says the messages in the log give "a clear account of the diversion".

The ACARS (Aircraft Communications Addressing and Reporting System) messages were published by Airframes and can be considered reliable for what was transmitted and when.

• At 07:51 GMT - The aircraft reports it is diverting to Paris Charles de Gaulle airport
• 07:54 - The crew tell Dublin operations that air traffic control has passed on a bomb-on-board threat
• 08:03 - The crew reports that the fuel level required to proceed to Rome is no longer assured
• 08:28 - Weather reports for Toulouse, Brest and Nantes, suggesting alternate destinations are being considered
• 08:40 - Plane reports diversion to Evreux Air Base, west of Paris, on government order

Chan, who is also a former airline pilot, says that although ACARS spoofing - the act of sending false messages - is possible, corroboration between the messages and known details of the affected flight makes it very unlikely in this case.

A spokesperson for Aeroporti di Roma tells the BBC that security checks have now been completed on a Finnair flight from Helsinki that landed safely at Rome Fiumicino Airport at around 09:30 this morning, following anonymous reports of a suspected bomb threat.

The aircraft was escorted into the airport by Italian Air Force fighter jets, while bomb disposal operations were launched in line with standard security procedures.

Police bomb disposal experts carried out the inspections, which returned a negative result, with no explosives found on board, according to information received from the airport.

The spokesperson said the security checks proceeded as normal and had no impact on airport operations.

A flight from Warsaw to Brussels - which we mentioned in our round-up earlier - has landed safely and no suspicious items were found, Polish airline LOT says.

"Following receipt of information regarding a potential security threat to flight LO235 from Warsaw to Brussels, the flight crew was notified of the situation and conducted an onboard inspection in accordance with established procedures," a LOT spokesperson says, according to Reuters news agency.

Security services carried out an additional inspection after landing, where "no dangerous or suspicious items were found", the spokesperson adds.

Nearly 200 passengers were evacuated from a Wizz Air flight travelling from Milan to Bucharest on Thursday following a bomb threat.

Flight WMT3064 landed safely at Bucharest’s Henri Coandă International Airport at 11:08 local time.

Airport officials said passengers had been evacuated and emergency procedures activated in cooperation with state institutions.

"Passengers have been disembarked. The airport has taken the procedural measures required in such cases, in cooperation with state institutions.

"A crisis management unit is being established, and specific procedures for these situations are being implemented," airport representatives told BBC.

A specialist explosives disposal team from Romania’s Intelligence Service (SRI) is inspecting the aircraft.

Bucharest National Airports Company said air traffic was operating safely and without disruption, with flights continuing according to schedule.

Police in the Czech Republic say they're "preparing for landing" of four flights heading to Prague, after "receiving a threat regarding the placement of an improvised explosive device".

"We assess the relevance of the threats as low," Czech police write on X, who say "pyrotechnic inspections will be conducted on all aircraft" after landing.

Across Europe, there are several reports of flights being impacted by bomb threats, with information still emerging.

So far on Thursday, those flights include:

• Aer Lingus Dublin to Rome, diverted to Evreux airbase
• Finnair Helsinki to Rome, landed in Rome
• Wizzair Milan to Warsaw, diverted to Vienna
• LOT Warsaw to Brussels, landed in Brussels

• Ryanair Copenhagen to Sofia, landed in Sofia
• Ryanair to Madrid to Sofia, landed in Sofia
• Ryanair London Stansted to Sofia, diverted to Plovdiv

We are working to confirm details with the respective airlines, and will provide further information shortly.
