TEHRAN, Iran (AP) — A U.S. Navy spokesman says no American drones are missing in the Middle East following Iranian claims it had captured an unmanned American surveillance aircraft.

Cmdr. Jason Salata, a spokesman for the U.S. Navy's 5th Fleet, says 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 says that U.S. ScanEagles have been lost into the sea in the past, but none have gone down recently.

Other nations in the Gulf, including the United Arab Emirates, have ScanEagle drones in service.

The 5th Fleet is based in Bahrain.
