IAEA Director General Rafael Grossi said on Monday he is concerned about Israel possibly targeting Iranian nuclear facilities, but that International Atomic Energy Agency (IAEA) inspections of Iranian facilities would resume on Tuesday.
Grossi said Iran closed its nuclear facilities on Sunday over "security considerations" and that while they reopened on Monday, he kept IAEA inspectors away "until we see that the situation is completely calm."
"We are going to resume tomorrow," Grossi told reporters in New York.
"This has not had an impact on our inspection activity."
Iran says its nuclear program is entirely peaceful, but Western powers accuse it of seeking to build nuclear bombs.
