Flights have been grounded because of the IT outage - a flaw which left many computers displaying blue error screens.

There were long queues, delays and flight cancellations at airports around the world, as passengers had to be manually checked in.

Cyber-security firm CrowdStrike has admitted that the problem was caused by an update to its antivirus software, which is designed to protect Microsoft Windows devices from malicious attacks.

Microsoft has said it is taking "mitigation action" to deal with "the lingering impact" of the outage.
