Qatar's Defense Ministry says two warplanes have collided on a training mission.
The ministry did not identify the types of aircraft involved in Wednesday's collision.
It says the pilots were safe after ejecting, without elaborating.
Qatar, a small nation on the Arabian Peninsula, has been targeted by a four-nation boycott for over two years now over a political dispute.
Qatar is home to the massive Al-Udeid Air Base, which hosts US Central Command's forward headquarters and thousands of American troops.
Lt. Col. Christine D. Millette of US Air Force Central Command says American officials are "aware of the Qatari midair collision, but we have not been asked for support at this time."
