Airports around the world are in chaos this weekend, with planes grounded and passengers left facing delays and cancellations.

The disruption began in America, when an air traffic outage brought flights across the US to a standstill.

Two major airports were closed on Friday, with travellers in Canada also experiencing a knock-on effect.

Europe was next to suffer, with several airports, including London Heathrow, experiencing problems due to a 'cyber attack' on Collins Aerospace.
