Iran has invited the United Nations nuclear agency inspectors to visit its unfinished reactor at Arak heavy water plant, which is capable of producing enough plutonium for up to two warheads a year.
The International Atomic Energy Agency (IAEA) head, Yukiya Amano, said that the body will accept the offer, the Washington Post reports.
His announcement came after a landmark nuclear deal between Iran and six world powers was signed last weekend.
