A cyber attack is causing disruption at several major European airports including Heathrow, Brussels and Berlin.
The attack targeted a business providing check-in and boarding systems for several airlines around the world.
With automated systems down, staff are having to conduct manual check-in and boarding procedures, according to Brussels Airport.
“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 caused by “a technical issue” at a third-party supplier and told passengers to check the status of their flight before travelling to the airport.
