The International Atomic Energy Agency (IAEA) said on Monday that there was "no indication" that Israeli and US strikes on Iran had hit any nuclear facilities.
At the Board of Governors meeting at the agency's headquarters in Vienna, Austria, IAEA Director General Rafael Grossi urged all parties in the conflict to exercise maximum restraint and called for the issue to be resolved through diplomatic measures.
Grossi also said that the current situation is extremely concerning, that regional security monitoring networks were on high alert, and that the possibility of a radioactive leak with serious consequences could not be ruled out.
Reza Najafi, Iran's ambassador to IAEA, said on Monday that Natanz, one of Iran's three key nuclear facilities, had been attacked by Israeli and U.S. forces.
The attacks against Iran came after U.S.-Iran nuclear talks concluded without agreement in Geneva on Thursday.

China is calling for an immediate cessation of the U.S.-Israeli attacks on Iran and joint efforts to oppose such unilateral actions, the Chinese envoy to the International Atomic Energy Agency (IAEA) said on Monday.
Li Song, China's permanent representative to the IAEA, said that military strikes against Iran, launched by the United States and Israel, have led to a sudden escalation of an already volatile situation in the Middle East.
Li said the attacks launched as the U.S. and Iran were in the midst of negotiations were unacceptable, as was the blatant killing of a sovereign leader and the incitement of regime change. China firmly opposes and strongly condemns such unilateral acts, Li said.
Li said that China respects Iran's legitimate right to the peaceful use of nuclear energy, and attaches great importance to Iran's repeated reaffirmations that it has no intention of developing nuclear weapons. He also highlighted a report released by IAEA Director General Rafael Grossi, which stated that no evidence of Iran developing nuclear weapons had been found.
Peacefully resolving the Iranian nuclear issue through political and diplomatic means is the only correct option and is in the common interest of the international community, Li said.
