A cyberattack has disrupted operations at several major European airports, including Heathrow, Brussels, and Berlin.

The attack targeted a company that provides check-in and boarding systems for multiple airlines worldwide.

With automated systems offline, staff at Brussels Airport said they have resorted to manual check-in and boarding procedures.

“This has a large impact on the flight schedule and will unfortunately cause delays and cancellations of flights,” it said in a statement on its website.

Heathrow warned of delays linked to “a technical issue” at a third-party supplier and advised passengers to confirm their flight status before heading to the airport.
