TEHERAN, Iran - Iran says it has determined that two spy planes it claims to have downed were operated by the United States. An Iranian official says authorities will publicly display them.

The Revolutionary Guard's air force said earlier this month that it shot down two highly advanced spy planes that had violated Iranian airspace. It provided no proof. Iranian officials have not clarified whether they were pilotless drones or another type of aircraft.

The US Navy's 5th Fleet, which is based in the Gulf, said at the time that it had no reports of any aircraft downed recently.

Iran's semiofficial Fars news agency on Saturday quoted the head of the Guard's naval force, Gen. Ali Fadavi, as saying Iran will display the two small reconnaissance planes "at an appropriate time."
