The chief of the U.N. nuclear watchdog announced that a team of inspectors has returned to Iran for the first time since Israeli and U.S. strikes targeted Iranian nuclear facilities earlier this year.

Iran suspended cooperation with the United Nations' International Atomic Energy Agency following a 12-day war with Israel in June, with Tehran pointing to the IAEA's failure to condemn Israeli and U.S. strikes on its nuclear facilities.

"Now the first team of IAEA inspectors is back in Iran, and we are about to restart," Director-General Rafael Grossi told Fox News' "The Story" in an interview aired Tuesday.

"When it comes to Iran, as you know, there are many facilities. Some were attacked, some were not," Grossi said.

"So we are discussing what kind of ... practical modalities can be implemented in order to facilitate the restart of our work there."
