London: A significant cyberattack on a third-party system provider has led to widespread flight disruptions at major European airports, including London's Heathrow, Brussels, and Berlin. The authorities have confirmed the issue, which has caused considerable inconvenience for passengers and airlines. According to Anadolu Agency, Brussels Airport has reported at least four flight cancellations, including key departures to Rwanda and Amsterdam, following the cyberattack. The attack disabled automated check-in and boarding systems, forcing the airport to resort to manual check-in procedures. This shift is expected to have a large impact on the flight schedule, with further delays and cancellations anticipated.
