World Health Organization Director-General Tedros Ghebreyesus said in a post to X on Sunday that strikes on Iranian nuclear facilities "could trigger a nuclear accident, with health impacts that would devastate generations."

"With every passing day of this escalating conflict, the stakes and threats are raised higher and higher. We must de-escalate now," Ghebreyesus said, following the latest report of attacks near Iran's Bushehr Nuclear Power Plant.

Iranian Foreign Minister Abbas Araghchi on Saturday accused the U.S. and Israel of striking close to the plant four times since Feb. 28. Iran's Atomic Energy Organization said one employee was killed in the latest strike near the facility on Saturday.

Iran's semi-official, Islamic Revolutionary Guard Corps-affiliated Tasnim News Agency on Sunday claimed that Iranian forces destroyed "several" U.S. aircraft which were involved in the operation to rescue the second F-15 crew member downed over Iran on Friday.

Other state-run and semi-official news agencies, among them the state-run Islamic Republic of Iran Broadcasting television station, also published the claim, which was attributed to a spokesperson for the Iranian military's Khatam Al-Anbiya Central Headquarters.

The spokesperson claimed that Iranian forces destroyed two C-130 aircraft, as well as two Black Hawk helicopters, Tasnim reported.

The Iranian military has previously made unconfirmed claims alleging damage to U.S. military assets. U.S. officials told ABC News that American forces destroyed two stuck C-130s during the rescue operation to avoid them falling into Iranian hands.

U.S. officials have also said that two Black Hawk helicopters were hit by incoming fire during the operation to retrieve the first of the downed F-15 airmen on Friday.
