Multiple flights across Europe were diverted following fresh bomb threats as cyberattacks on critical infrastructure raised security concerns. Several passenger flights across Europe were forced to make emergency or unplanned landings on Thursday after fresh bomb threats targeted aircraft flying from major cities, triggering security alerts in France, Bulgaria, Belgium and other parts of the continent. The latest incidents come days after similar threats disrupted air travel across Europe, with at least seven flights and a cruise ship receiving bomb threats on Tuesday. No explosive devices were found in the earlier incidents. Among the flights affected on Thursday was Aer Lingus flight EI402 from Dublin to Rome, which was diverted to Evreux airport in France, around 100 km west of Paris. The aircraft landed safely after being diverted as a security precaution, the Irish airline said. According to the French Prime Minister's office, all 151 passengers and six crew members aboard the aircraft were safe. Bomb disposal teams were deployed to examine the plane. A Finnair flight from Helsinki to Rome was also targeted by a bomb threat. The aircraft was escorted by the Italian air force and landed safely at its scheduled destination, with no suspicious material found during subsequent checks. In Bulgaria, three aircraft were forced to make emergency landings following bomb threats. Flights from Copenhagen and Madrid landed in Sofia, while another aircraft travelling from London landed in Plovdiv. Belgian media also reported that a Polish LOT Airlines aircraft was forced to land at Brussels' Zaventem airport following a security alert. The latest wave of threats has raised fresh concerns over the vulnerability of European aviation infrastructure, particularly as the incidents coincide with a series of suspected cyberattacks targeting essential services across the continent. The repeated alerts have also raised questions about whether the incidents could be part of a broader pattern of low-cost, difficult-to-trace disruption targeting critical infrastructure. The aviation disruptions come amid a separate wave of cyberattacks targeting refrigeration systems at supermarkets across Europe. Hackers reportedly manipulated temperature controls in refrigerators and freezers, with some units remotely set to 50 degrees Celsius (122 degrees Fahrenheit), while others were switched to defrost mode. The attacks affected retailers across eight European countries, forcing stores to discard large quantities of fresh and frozen food and resulting in losses worth millions of euros. France's national blood service, the French Blood Establishment (EFS), was also affected by a cyber incident on November 2. The attack targeted refrigeration equipment supplied by a third-party provider, affecting temperature monitoring and control systems at three regional facilities. The attackers attempted to raise temperature and defrost thresholds in cold-storage rooms containing plasma and blood samples. However, monitoring systems detected the changes, allowing staff to secure or transfer the stored products. The EFS confirmed that no blood products or samples were lost and that there was no interruption to blood collection or distribution. France's Health Ministry and national cybersecurity agency are investigating the incident.
