Earlier in the day, the Atomic Energy Organization of Iran (AEOI) said that Israel and the United States attacked the Natanz uranium enrichment facility, with no leaks reported.
"This is a blatant violation of international law, the charters of the UN and the IAEA [International Atomic Energy Agency], as well as relevant resolutions of the UN Security Council and the Agency's General Conference," Zakharova said in a statement.
The US and Israel continue to launch massive strikes against Iranian military, civilian, and "most dangerously of all - nuclear facilities, with no regard for civilian casualties or the potential radiological and environmental consequences," the spokeswoman added.
The UN and the IAEA must objectively assess the US and Israeli attack on the uranium enrichment facility in Iran, Zakharova said.
