DUBAI, April 5 (Reuters) - Several aircraft were destroyed in the south of Iran's ‌Isfahan province during a U.S. mission ‌to find a stranded airman, Iranian military officials ​said on Sunday.

U.S. officials told Reuters late on Saturday that a second airman whose F-15 jet was downed on Friday in Iran ‌was rescued, a ⁠day after the first crew member was recovered.

"Additional investigations by experts ⁠on the ground revealed that two C-130 military transport planes and two Black Hawk ​helicopters of ​the US army ​were destroyed by ‌our forces," the spokesperson of the unified command of Iranian armed forces said.

Separate statements by the Iranian army and Revolutionary Guards said an Israeli Hermes-900 drone as well ‌as a U.S. MQ-9 ​drone were downed in Isfahan ​province.

Reuters could ​not immediately verify the Iranian ‌accounts.

Iran's semi-official Fars news agency ​said U.S. ​search operations were conducted from Saturday evening in three different provinces, namely Chaharmahal ​and Bakhtiari, ‌Kohgiluyeh and Boyer Ahmad, and Isfahan.
