On Friday, bomb alerts targeted more than ten flights departing from or heading to Prague and Sofia, according to what was announced by the Czech capital's airport and the Bulgarian Ministry of Transport. Many officials linked this campaign, which has been ongoing for a week, to Europe's support for Ukraine in its war against Russia, and accused Moscow of waging a campaign of unrest "by all means" that represent low-cost, easy-to-deny methods and are not expected to call for an armed response.

This week, European flights are witnessing a wave of bomb threats, the latest of which was on Friday, when the Spanish Foreign Minister said that the continent appears to be facing “aggression by all means and a form of psychological warfare.”

In this context, a new wave of bomb threats were issued to target passenger flights across Europe for the third time this week.

Bulgarian media reported that two passenger planes coming from London and Brussels landed safely at an airport in Sofia on Friday after receiving bomb threats via email.

The Bulgarian Ministry of Transport told Nova TV that border police and security teams searched the two planes after the threats were received, but no suspicious items were found.

False threats disrupt dozens of flights

The false threats disrupted dozens of European flights on Thursday, forcing some planes to land other than their scheduled destination and prompting the dispatch of fighter planes to escort or intercept other planes, in a major escalation after the first wave on Tuesday.

No explosive devices were found and all planes landed safely.

Danish police said on Friday that they were investigating threats targeting air traffic at Copenhagen Airport, but concluded after a preliminary assessment that there was no danger to passengers. The airport said that it was "operating normally."

For its part, the Czech police said that they had received bomb threats on flights departing from and heading to Prague. An airport spokesman said that the threats included four arriving flights and five departing flights, but no explosive devices were found and no flights were canceled or diverted because of them.

A source at the Italian Airports Authority said shortly afterwards that a Wizz Air flight heading from Prague to Rome was diverted to Venice and landed there safely.

The French Prime Minister's office spoke about the receipt of four new bomb threats to target aircraft flying over French territory, and said that all of them landed safely.

CNN Portugal reported that a bomb warning aboard a Ryanair flight from Rome to Lisbon led to a security operation being carried out upon landing.

Security experts said Thursday that the threats bear the characteristics of a coordinated “attack by all means,” but it is always possible that individuals made imitated threats or acted out of personal grievances.

No country has attributed responsibility for the threats to a specific party, but they come after a wave of acts of sabotage and attempts to target sites across Europe, ranging from German power plants and defense-related facilities in the Baltic region to supermarket refrigerators in France and elsewhere, and Leipzig Airport in Germany.

Many officials linked this campaign to Europe's support for Ukraine in its war against Russia, and accused Moscow of waging a campaign of unrest "by all means" that represents low-cost, easy-to-deny methods and is not expected to call for an armed response.
