There is a problem with some of O'Hare Airport's runway lights.

The lights were flickering on at least three runways as of 10 p.m. Thursday. Planes are no longer using those runways for takeoffs or landings and crews are trying to fix the problem.

It's not clear yet now flights are being affected.
