A US fighter jet has been shot down over Iran and a search-and-rescue operation is underway for any survivors, two US officials told Reuters on Friday, in the first such known incident since the war began nearly five weeks ago.
The Pentagon and US Central Command did not respond to requests for comment.
The prospect of US pilots being alive and on the run inside Iran raises the stakes for the United States in a conflict that has struggled to win popular support among Americans, according to opinion polls.
It also presents a challenge to the US military, which faces the twin goals of trying to save the lives of any surviving US crew and safeguard whoever is involved in perilous rescue missions.
Iranian officials called on civilians to be on the lookout for survivors and have flooded social media with images that purport to show wreckage from the aircraft.
The governor of Kohgiluyeh and Boyer-Ahmad province said anyone who captured or killed the crew "would be specially commended," Iran's semi-official news agency ISNA reported
