Official: Iran Has Evidence It Captured US Drone A prominent Iranian lawmaker says Tehran has material evidence to prove that it has captured an American unmanned aircraft. The head of the Iranian parliament's defense committee Ismaeil Kowsari wouldn't specify what proof the Islamic Republic has to back up his claims. But he said Wednesday that Tehran will release more information on the aircraft soon. Iran claimed on Tuesday that it captured a Boeing-designed ScanEagle drone recently after it entered Iranian air space over the Persian Gulf. Cmdr. Jason Salata, a spokesman for the U.S. Navy's 5th Fleet, said Tuesday that all U.S. drones in the region are "fully accounted for."
