Iran's Foreign Minister Abbas Araghchi has accused the US of violating the UN Charter and international agreements with its bombing attacks on nuclear sites in his country.
"The United States, a permanent member of the United Nations Security Council, has committed a grave violation of the UN Charter, international law and the NPT [Treaty on the Non-Proliferation of Nuclear Weapons] by attacking Iran's peaceful nuclear installations," he wrote on X, formerly Twitter.
"The events this morning are outrageous and will have everlasting consequences, Araghchi said, stressing that "this extremely dangerous, lawless and criminal behavior" must alarm every UN member.
"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."

No increase in 'off-site' radiation after strikes — IAEA
The UN's nuclear watchdog has said radiation levels have not increased outside the sites bombed by the US, even in Fordo, the hardest-hit target.

"IAEA will provide further assessments on [the] situation in Iran as more information becomes available."
