Iran has yet to allow international inspectors access to nuclear sites bombed by Israeli and U.S. forces in June, according to a new confidential International Atomic Energy Agency report to member states, excerpts of which were published by Reuters on Wednesday.

“The Agency’s lack of access to this nuclear material in Iran for five months means that its verification … is long overdue,” according to the report.

“It is critical that the Agency is able to verify the inventories of previously declared nuclear material in Iran as soon as possible in order to allay its concerns … regarding the possible diversion of declared nuclear material from peaceful use,” the IAEA report continued.
