Iran invites UN watchdog to visit Arak plant next month

Iran has invited UN inspectors to visit a nuclear-related heavy water facility on Dec. 8, their chief said on Thursday, a first concrete step under a plan to clarify concerns about Tehran's disputed nuclear program.

Yukiya Amano, director general of the International Atomic Energy Agency, also said the IAEA was looking into how Sunday's agreement between Iran and six world powers to curb the country's atomic activity could be "put into practice" concerning the UN agency's role in verifying the deal. (Reuters)
