U.N. nuclear watchdog inspectors arrive in Iran


TEHRAN, Iran  — An Iranian news agency says inspectors from the U.N. nuclear agency have arrived in Tehran to visit a nuclear facility that has long been off-limits to outside experts.

The semiofficial Mehr news agency said today that two inspectors from the International Atomic Energy Agency will visit the heavy water production plant in the central city of Arak on Sunday. It didn’t provide further details.

Iran agreed last month with the IAEA to allow expanded U.N. monitoring at the country’s nuclear sites, including the Arak facility.

That agreement was not part of a separate interim deal that Iran also struck last month with world powers. The six-power deal commits Tehran to freeze its nuclear program for six months in return for limited relief from economic sanctions.
