The U.N. nuclear watchdog said on Friday it had pulled its last remaining inspectors from Iran as a standoff over their return to the country's nuclear facilities bombed by the United States and Israel deepens.

Iran's parliament has now passed a law to suspend cooperation with the IAEA until the safety of its nuclear facilities can be guaranteed. While the IAEA says Iran has not yet formally informed it of any suspension, it is unclear when the agency's inspectors will be able to return to Iran.
