A second wave of bomb threats attacked airliners across Europe today, November 5, forcing emergency landings, military escort and security operations. About 10 flights were affected, including an Aer Lingus flight from Dublin to Rome that was diverted to a French military base. Three Ryanair flights made emergency landings in Bulgaria, while four planes approaching Prague received bomb threats. The incidents follow similar threats against at least seven flights on November 3. No explosives were found. Authorities have not identified those responsible, although it is highly likely that the incidents were coordinated - probably by a rival European country. The threats are clearly designed to disrupt European infrastructure, perhaps as part of a broader campaign of hybrid warfare.
