A U.S. F-35 fighter jet made an emergency landing at a regional American airbase in the Middle East after conducting a combat mission over Iran, the U.S. military confirmed Thursday.

The aircraft, valued at up to $100 million, landed safely at the undisclosed base following the incident. CNN reported that two unnamed sources indicated the plane was believed to have been hit by Iranian forces during the mission.

The emergency landing occurred after the F-35 completed its combat operations over Iranian territory. Military officials have not provided specific details about the nature of the mission or the extent of any potential damage to the aircraft.

The incident comes amid ongoing tensions in the Middle East region. The F-35 Lightning II is one of the most advanced fighter jets in the U.S. military arsenal, designed for stealth operations and equipped with sophisticated electronic warfare capabilities.

U.S. military personnel are likely conducting a thorough assessment of the aircraft to determine what caused the emergency landing and whether any damage was sustained during the mission over Iran.
