Iran says it will not allow American or Canadian inspectors working for the U.N. nuclear watchdog to visit its nuclear facilities.

Deputy Foreign Minister Abbas Araghchi said Iran will only allow inspectors from countries that have diplomatic relations with it, in remarks broadcast by state TV on Thursday.

The previously undisclosed remarks were made during a Sunday meeting with parliamentarians.

Iran and world powers reached a historical deal earlier this month aimed at curbing Tehran's disputed nuclear program in exchange for the lifting of international sanctions.

The U.S. and Iran severed diplomatic relations after the 1979 Islamic revolution and the hostage crisis at the U.S. Embassy in Tehran.
