About 1,400 passengers of the Polish airline LOT were grounded at Warsaw's Chopin airport Sunday after hackers attacked the ground computer systems used to issue flight plans, the company said.

The computer system was hacked in the afternoon and fixed after about five hours, during which 10 of the state-owned carrier's national and international flights were canceled and about a dozen more were delayed, spokesman Adrian Kubicki said.

LOT was taking care of the passengers Sunday evening, and some were already able to board flights. LOT said it was providing hotels for those who needed to stay overnight.

At no point was the safety of ongoing flights compromised, Kubicki said, and flights destined for Warsaw were able to land safely. No other airports were affected, he added.

"We're using state-of-the-art computer systems, so this could potentially be a threat to others in the industry," Kubicki said. The attack is being investigated by the authorities.

The airport itself wasn't affected, its spokesman said.
