Iranian military aircraft were reportedly only minutes away from striking a key American installation in Qatar before they were intercepted and shot down by Qatari fighter jets, according to a report by CNN citing two unnamed officials familiar with the incident.

The report said the Iranian aircraft were just “two minutes” from launching an attack on Qatar’s al-Udeid Air Base — the largest U.S. military facility in the Middle East — when Qatari F-15 fighter jets engaged and destroyed them.

According to one of the sources briefed on the situation, the aircraft were identified as Soviet-era Su-24 tactical bombers operated by Iran’s Revolutionary Guards. The planes were reportedly flying toward al-Udeid, which typically hosts about 10,000 U.S. service members, as well as Qatar’s Ras Laffan natural gas processing complex.

The source said the aircraft were carrying “bombs and guided munitions” and did not respond to repeated radio calls as they approached their suspected targets.

Officials said the Iranian aircraft ultimately went down in Qatari territorial waters after being struck by the fighter jets. Search operations are currently underway to locate the crews of the downed planes.
