Iran and the U.N. nuclear watchdog said on Tuesday they had reached a deal on resuming inspections at sites including those bombed by the U.S. and Israel but gave no specifics, and Tehran warned the West the deal was off if sanctions were re-imposed.

Iran and the International Atomic Energy Agency have signed an agreement in Cairo to open the way for resuming cooperation, including on ways of resuming inspections of Iran’s nuclear facilities.

Iran has not allowed inspections since its nuclear sites were bombed by Israel and the United States in June, but it hopes to stave off Western economic sanctions.
