Cyber attack on check-in systems disrupts flights in London, Berlin, and Brussels.

A massive cyber attack targeted a provider of airport check-in and boarding systems on Saturday morning, disrupting some of Europe's major airports.

Boarding operations are interrupted in Brussels, Berlin and London Heathrow, where flight delays and cancellations are being recorded.

At Brussels Airport, the attack disabled automated systems, allowing only manual check-in and boarding. At least ten flights were canceled in Berlin.
