Iranian forces shot down a U.S. fighter aircraft over the country, state media said on Friday.

The well-being of the crew remains unknown, but there is reportedly a search-and-rescue operation underway for the pilot. U.S. Central Command has not commented publicly on the matter. Several U.S. outlets confirmed Iran state media’s report, citing anonymous U.S. officials. Pictures of what appeared to be an ejected fighter pilot’s seat flooded social media.
