European air traffic targeted by new threats after a week of hoaxes

No suspicious items were found and no one was injured, but the threats have raised concern because they came as Europe digests a host of other recent disruptions — including attacks on supermarket refrigeration systems and drone incursions.

Overall, the threats have caused minimal disruption to aviation across the continent, according to the European air traffic authority.

Eurocontrol said it was aware of bomb threats against 14 flights on Thursday — only 0.05% of all of the nearly 26,300 flights across the European network that day — and seven on Tuesday.

The European Union’s transportation commissioner, Apostolos Tzitzikostas, said there were 11 more on Friday.

Mr Tzitzikostas said after a meeting with Eurocontrol and the EU’s Aviation Safety Agency in Brussels that security experts will meet in the Belgian capital next week to discuss measures needed to deal with the rash of bomb threats.

“Our priority here is clear. The safety of passengers and the smooth functioning of European aviation,” he said.

In Hungary, the defence minister said military fighter jets escorted three separate passenger planes across the country’s airspace within an hour after each received bomb threats. Romulusz Ruszin-Szendi said they were flights from Brussels to Sofia and from Prague to Cyprus and Romania.

French Prime Minister Sebastien Lecornu’s office said on Friday that “four new bomb threats were made today against aircraft flying over French territory”.

The planes landed safely and bomb disposal experts were conducting inspections.

Other incidents included threats against a Prague to Bucharest flight operated by Romanian carrier Tarom, and a Ryanair flight travelling from Lisbon to Rome. Security inspections were carried out and no explosives were found.

A WizzAir flight from Prague to Rome was diverted to Venice after a bomb alert, and passengers were evacuated after the aircraft landed. Air traffic at the airport was briefly suspended, but police searches turned up nothing.

At Prague’s Vaclav Havel Airport, spokesperson Denisa Hejtmankova said a total of nine flights were threatened, including arriving flights from Denmark, Spain and Britain, and departing flights to the Netherlands, Cyprus, Romania, Italy and Britain.

Czech police said security measures were taken that had “a minimal impact on the normal operations at the airport”.

In the Danish capital, Copenhagen, police said on Friday they went to the airport for a second consecutive day “in connection with threats directed at air traffic” as a precautionary measure. They said they assessed that there had been no danger to passengers or to others at the airport.

More than two dozen flights were affected by threats earlier in the week, with some diverted as authorities scrambled to rule out any danger.

Fake bomb threats are relatively common but it is unusual to see so many in such a short period.

It remains unclear who is behind the wave of airline hoaxes, which come at a time of increased geopolitical tensions and warnings from authorities that Russia may be ramping up so-called hybrid threats in Europe.

Italian prime minister Giorgia Meloni said that the recent cyberattacks and bomb threats are cause for concern.

“Today we are not in a position to say whether these events are all connected,” she said on the sidelines of an event in Verona. “But they certainly tell us the same thing: that civilian infrastructure is under attack.”

Authorities have not attributed the threats to any group or state actor, and no evidence has emerged linking the hoaxes to a government.

An email containing the threat sent on Thursday to airport authorities in Rome and reviewed by the Associated Press purported to come from a group describing itself as anti-feminist and claiming it was targeting a “feminist regime”.

Another European airport received a threat with similar wording, but it was unclear if it came from the same sender.

Bomb threats are on pilots’ minds and create unnecessary tension, but crews are prepared to respond professionally, said Paul Reuter, vice president of the European Cockpit Association. Pilots review procedures with cabin crews, identify airports where they could divert and may carry extra fuel, he said.

Mr Reuter called the use of civil aviation for geopolitical disruption or hoaxes “totally unacceptable”.

In Ireland, the Dublin headquarters of national broadcaster RTÉ was evacuated on Friday after a bomb threat, and live broadcasts were replaced with pre-recorded programmes.

Ireland’s police force, An Garda Síochána, said it was “aware of a threat made against media organisations here and in Europe”.

It said that it has been liaising with Irish media organisations and the threat will be investigated.

Irish Prime Minister Micheál Martin said the threats to RTÉ and others “just illustrate how relatively simple it can be to cause disruption and to undermine the normal operation of society through unconventional activities of this kind, which are designed to cause fear and anxiety”.

Separately, UK-based broadcaster Sky said it had also received a “security threat”. In a statement reported by Sky News, which remained on air, it said that “we are working closely with authorities to ensure our people and operations remain secure”.

Meanwhile, Nova TV, a private broadcaster in Bulgaria, said it received an email on Friday threatening it with a bomb.

It said the sender claimed to be behind the threats to European air traffic, and that the broadcaster implemented its standard safety measures without any interruptions to its TV and radio broadcasts.
