U.S. officials would not say where the aircraft crashed. The Air Force was working to notify the pilot’s family on Monday.
Recent airstrikes in Iraq and Syria have been carried out from several bases in the Persian Gulf region, including Al Udeid Air Base in Qatar, Ali al Salem Air Base in Kuwait and al Dhafra Air Base in the United Arab Emirates. Warren declined to say which base was used to launch the F-16, saying it is Defense Department policy not to do so.
