Video footage, which has been seen by CNN and other outlets, shows a plane in flames falling in a spiraling trajectory. Another video appears to show the pilot ejecting with a parachute. The video has been located in an area near al-Jahra in Kuwait.
According to analysts, the plane is an American model, an F-15E or an F/A-18. It is unclear which country operated it.
Kuwait's Ministry of Defense said in an initial statement that several U.S. fighter jets had crashed, but that the crews had survived, AFP writes.
The region has been shaken by attacks and counterattacks after the U.S. and Israel's major attack on Iran this weekend.
