(Reuters) - All flights into and out of Chicago's O'Hare and Midway international airports were grounded early on Friday due to a fire at an air traffic control facility, the Federal Aviation Administration said.
Employees at the facility in Aurora, Illinois, were evacuated and a fire department was on the scene, the FAA said.
More than 300 flights into and out of the two airports had been canceled by 7:30 a.m. CT (1230 GMT) on Friday, according to the tracking website FlightAware.com.
Crews responding to the fire found a man with self-inflicted wounds in the basement of the facility, the Chicago Tribune reported.
The man was taken to a hospital, the newspaper said, citing an Aurora Police Department spokesman.
Police could not be immediately reached for comment.
