Cyber incidents continue to cause chaos across major European airports.

Dublin, Berlin, Brussels and London's Heathrow are thought to be experiencing cyber attacks, knocking out online baggage and check-in systems.

It's the third day of technical failures, with dozens of flights delayed or cancelled.

Europe correspondent Gavin Gray told Francesca Rudkin that the issue is with a widely-used system by Collins Aerospace, which allows airlines to use the same check-in desks and boarding gates.

He says things are going wrong and many airlines are having to use manual boarding and check-in with paper and pen.
