A cyber attack caused flight delays and cancellations at Brussels Airport in Belgium. The airport operator said that "the attack affected the functioning of automated systems, so only manual check-in is possible." They noted that "this disruption has a major impact on the flight schedule, and the service provider is trying to fix the problem quickly." Passengers with flights scheduled for today were asked to check with airlines before arriving at the airport. The Berlin Airport website stated that "due to a technical issue with the systems provider across Europe, check-in waiting times are longer."
