Bomb threats forced European airlines to reroute additional passenger flights on Thursday, following a series of warnings earlier in the week that disrupted operations. According to Sina Finance, a Wizz Air Holdings Plc flight from Milan to Warsaw diverted to Vienna after receiving a threat midflight, while a Dublin-to-Rome flight was diverted to a military base in Évreux, Normandy. Aer Lingus said flight EI402 landed safely after diverting to Normandy for security reasons; it carried more than 150 passengers and six crew members, and the airline said it would arrange onward travel. A LOT Polish Airlines flight from Warsaw to Paris was stopped while taxiing and directed to a stand for security checks. Authorities said no dangerous items were found and airport operations later resumed. The threats this week have shown no discernible pattern, and bomb threats are uncommon and almost always hoaxes. More than 30,000 flights take off and land in European airspace on an average day. The rise in threats comes amid heightened geopolitical tensions and other unusual disruptions, including repeated hacks of supermarket refrigeration systems and drone incursions into European airspace.
