U.S. officials have denied claims by the Iranian government that it has captured an American surveillance drone.
Iranian state TV showed images of what seemed to be an intact ScanEagle drone.
Iran said that its Revolutionary Guard captured the unmanned drone after it entered Iranian airspace over the Persian Gulf.
Cmdr. Jason Salata, a spokesman for the U.S. Navy's 5th Fleet, said all U.S. drones in the region are "fully accounted for."
He also cast doubt on Iranian claims Tuesday that the U.S. ScanEagle drone entered Iranian airspace, saying U.S. operations in the Persian Gulf are "confined to internationally recognized water and airspace."
He said that U.S. ScanEagles have been lost into the sea in the past, but none have gone down recently.
Last month, Iran fired on a U.S. drone that it claimed violated its airspace. The Pentagon said that was not true.
