April 3 (UPI) -- The U.S. forces rescued at least one crew member after Iran shot down a U.S. F-15E fighter jet Friday, unnamed U.S. military sources told multiple media outlets.

Officials confirmed the rescue to CBS News but said search-and-rescue operations were still taking place. CNN reported they were looking for one other pilot before Iranian forces could reach them. The F-15E has a standard crew of two pilots, The New York Times reported.

Iran's state-run Tasnim news agency reported that Iranian officials' efforts to locate the two U.S. pilot had "so far been unsuccessful." Another Iranian news outlet, Fars News, said the government was offering a reward to anyone who captured an "enemy pilot or pilots."

Iranian media outlets published photos of what appears to be a shot-down F-15 fighter jet.

White House press secretary Karoline Leavitt told CNN that President Donald Trump had been briefed on the incident.

This is the first U.S. aircraft to be shot down by Iran since the start of U.S. and Israeli bombing on Feb. 28. Three other F-15 jets were shot down by mistake in Kuwait.
