ANKARA (AA) - Turkish Airlines said Wednesday that its operations have returned to normal after technical issues with its ticket reservation and booking systems led to the cancellation of all flights departing from Istanbul.

"There was no cyberattack-related issue," senior vice president for media relations Yahya Ustun said on X.

Due to work to restore normal operations, the airline canceled all flights departing from Istanbul between 7 p.m. and 10 p.m. local time (1600GMT-1900GMT) on Wednesday.

The national flag carrier announced that ticketing and reservations had been interrupted due to maintenance work to address the issue.

It said it would compensate for all expenses related to accommodation, refunds and any other costs incurred due to canceled flights.
