Following the U.S. attacks on three Iranian nuclear facilities -- Fordow, Natanz and Isfahan -- on Saturday, the International Atomic Energy Agency said early Sunday that "no increase in off-site radiation levels has been reported as of this time."

"IAEA will provide further assessments on [the] situation in Iran as more information becomes available," the agency said in a post to X.

Mohammad Reza Kardan, the deputy director of Iran's Atomic Energy Organization, said no radiation had been observed outside the facilities, attributing this to advance safety planning. He condemned the attacks as a "criminal act" and a first in global history, warning of violations of international law.

Iranian officials said residents near the sites remain safe and are continuing their lives "without worry" despite the strikes.

The Israel Defense Forces said early Sunday that ballistic missiles were launched from Iran toward Israel following the U.S. strikes on Iranian nuclear facilities.

Around 30 minutes after its first warning, the IDF said Iran launched a second wave of missiles toward the country.

Iran's Foreign Minister Abbas Araghchi said in a post to X in the early hours of Sunday that the U.S. strikes on Iranian nuclear sites were "outrageous and will have everlasting consequences."

"Each and every member of the UN must be alarmed over this extremely dangerous, lawless and criminal behavior," Araghchi said.

"In accordance with the UN Charter and its provisions allowing a legitimate response in self-defense, Iran reserves all options to defend its sovereignty, interest and people," he added.
