The United Nations’ top nuclear oversight official has arrived in Tehran for talks with the Iranian government. The visit from International Atomic Energy Agency chief Yukiya Amano comes ahead of a key summit in Baghdad between Iran and world powers, including the United States later this week. Ahead of his visit, Amano said he is optimistic that a new framework for monitoring Iran’s nuclear sites can be reached.

Yukiya Amano: “We need to keep up the momentum. There has been good progress during the recent round of discussions between Iran and IAEA, so I thought that now is the right time for me to visit Tehran and have a direct talk with high-level officials of Iran.”
