-- An F-16 fighter jet with the Arizona Air National Guard crashed Tuesday afternoon in southeastern Arizona, officials said.
A male pilot died in the crash, the Graham County Sheriff's Department said Tuesday night. The Arizona Air National Guard has yet to comment on the status of the pilot.
A statement posted late Tuesday afternoon on the Facebook page of the Arizona Air National Guard's 162nd Wing, of which the F-16 Fighting Falcon is based out of, read, "Rescue efforts are underway and the status of the pilot is unknown at this time."
The crash happened at 3 p.m. about 20 miles northwest of Safford, Arizona.
The U.S. Air Force has assembled an interim safety board to investigate the incident.
