EUROPE — November 5, 2026 — A wave of bomb threats disrupted air travel across Europe on Thursday, affecting at least 14 passenger flights and forcing several aircraft to change routes, make emergency landings, or receive military fighter jet escorts.
Flights involving airports in Dublin, London, Madrid, Copenhagen, Milan, Warsaw, Helsinki, and other European cities were affected, prompting extensive security operations across multiple countries.
All affected aircraft landed safely, and authorities reported that no explosives had been discovered during security inspections.
The incidents mark the third day of similar threats this week, with more than 20 bomb alerts reported across European aviation networks.
Passenger Plane Diverted to French Military Base
One of the most significant incidents involved Aer Lingus flight EI402, traveling from Dublin, Ireland, to Rome, Italy.
The Airbus A320, carrying 151 passengers and six crew members, was diverted to Évreux military air base in Normandy, France, after authorities received a bomb threat.
French military aircraft were dispatched to escort the passenger plane, while emergency personnel and bomb disposal specialists prepared for its arrival.
The aircraft landed safely, and passengers and crew were moved to a secure location while security teams inspected the plane.
French authorities confirmed that the situation was closely monitored by the government.
Italian Fighter Jets Escort Finnair Aircraft
Another security alert affected a Finnair flight traveling from Helsinki, Finland, to Rome’s Fiumicino Airport.
Italian Air Force fighter jets intercepted and escorted the passenger aircraft to its destination following a bomb threat.
The plane landed normally, and specialized security teams conducted inspections.
Authorities later confirmed that nothing suspicious had been found, and regular operations at Rome’s airport continued without significant disruption.
A separate Finnair flight from Helsinki to Vienna also received a similar threat.
Three Ryanair Flights Targeted in Bulgaria
Bulgarian authorities reported bomb threats involving three Ryanair flights traveling to Sofia from Madrid, Copenhagen, and London Stansted.
The aircraft from Madrid and Copenhagen continued to Sofia under heightened security precautions.
The flight from London was diverted to Plovdiv Airport in eastern Bulgaria.
Bulgarian military fighter jets escorted the aircraft as part of the country’s emergency aviation security procedures.
All three planes landed safely, and subsequent inspections found no explosive devices.
Flights Diverted in Poland, Austria, and the Czech Republic
The security alerts also disrupted flights operated by several other European airlines.
A Wizz Air flight traveling from Milan to Warsaw was redirected to Vienna after receiving a bomb threat.
A LOT Polish Airlines flight from Warsaw to Brussels was also subjected to additional security procedures.
Meanwhile, Czech authorities reported threats targeting four aircraft scheduled to arrive at Prague Airport.
Police described the threats as having low credibility but emphasized that all necessary security measures were being implemented.
Two flights arriving in Copenhagen were also investigated following similar warnings.
More Than 20 Bomb Threats Reported This Week
Thursday’s incidents followed a series of similar alerts earlier in the week.
On Tuesday, November 3, approximately ten flights were targeted by bomb threats, prompting emergency inspections, flight diversions, and the temporary closure of an airport in Warsaw.
Another incident on Monday forced a Wizz Air flight traveling from London Luton to Sofia to divert to Budapest.
European aviation authorities have reported more than 20 bomb threats during the week, with Ryanair among the most frequently targeted airlines.
Despite the scale of the disruption, no explosive devices have been discovered in the inspected aircraft.
Are the Threats Connected?
European authorities are investigating whether the incidents are linked or represent separate attempts to disrupt civilian aviation.
Many of the threats were reportedly delivered through anonymous emails, making their origins difficult to establish.
European Union officials have activated an aviation security information-sharing mechanism to improve coordination among national authorities.
Although the incidents have occurred during a period of heightened geopolitical tensions, investigators have not publicly identified the individuals or organizations responsible.
There is currently no confirmed evidence linking the bomb threats to a particular foreign government or coordinated terrorist operation.
Growing Concerns About European Aviation Security
The repeated threats have raised concerns about the vulnerability of civilian aviation to large-scale disruption.
Even when threats prove false, airlines and airports must respond with emergency procedures that can involve evacuations, military escorts, specialized security inspections, flight diversions, and extensive delays.
These operations create financial costs for airlines and airports while causing significant disruption for passengers.
The incidents also demonstrate how anonymous threats can affect multiple countries simultaneously without any explosive device being present.
European authorities continue investigating the origin of the warnings while emphasizing that passenger safety remains the highest priority.
For now, the most important confirmed development is that all affected aircraft landed safely and no explosives were found.
The investigation remains ongoing.
