European flights diverted after second wave of bomb threats

European flights were disrupted across multiple countries this week due to bomb threats, with around 10 flights affected on Thursday and several diverted. The wave of threats followed similar incidents on Tuesday, when at least seven flights and a cruise ship were impacted, though no devices were found.

Authorities have not attributed responsibility to any country for the threats. Officials have linked the events to broader concerns about hybrid-style disruptions in Europe, while Moscow and Tehran deny involvement in such campaigns.

Bulgarian officials reported emergency landings for three aircraft amid the threats, with planes from Copenhagen, Madrid, and London diverted to Sofia and Plovdiv. In Prague, four planes headed for the city reportedly received threats, though police stated the credibility of these threats was low and security measures were activated.

Airlines and airports involved included Aer Lingus, Finnair (operated by Jettime), and LOT, among others. Diversions resulted in landings at Evreux (France) and Brussels, with several other flights continuing to Vienna after threat calls and inspections. In Brussels, a LOT flight from Warsaw landed safely after a security review found no threat.

Industry commentary noted that repeated threats could serve to disrupt operations and test response by airlines and authorities. The comments also pointed to a broader pattern of disruption affecting essential services across Europe, alongside recent cyber incidents targeting supermarket refrigeration systems.
