The head of the United Nations' nuclear watchdog says a "roadmap" has been signed between it and Iran as a final deal has been struck over the Islamic Republic's contested nuclear program.
Yukiya Amano, the head of the International Atomic Energy Agency, made the comments in Vienna on Tuesday, just a short time after diplomats acknowledged a deal had been made between world powers and Iran.
Amano said Ali Akbar Salehi, the head of Iran's nuclear program, signed the roadmap. It calls for his agency, with Iran's cooperation, to make an assessment of issues relating to possible military dimensions of the Islamic Republic's nuclear program by the end of 2015.
Amano says: "This is a significant step forward toward clarifying outstanding issues regarding Iran's nuclear program."
