'HACKERS' CRIPPLE BRITISH AIRWAYS -- UK THREAT LEVEL SEVERE
British Airways canceled all flights from London's Heathrow and Gatwick airports Saturday as a global IT failure causes severe disruption for travelers.
The airline said it was suffering a "major IT systems failure" around the world. It didn't say what was causing the problem but said there is no evidence of a cyberattack.
BA said terminals at Heathrow and Gatwick had become extremely congested and cancelled all flights from those airports until 6 p.m. (1700GMT, 1 p.m. EDT). It is urging passengers not to go to the airports.
BA has not said what is causing the computer failure. It said in a tweet that the problem is global.
