The International Atomic Energy Agency specifies that amount in a confidential note dated today and shared with The Associated Press.
IAEA chief Yukiya Amano is expected to ask the agency's 35 board members during a December 11 meeting for contributions to pay for further policing of Iran's compliance with an interim agreement capping nuclear programs that could be turned to military uses.
A comprehensive accord will replace that deal signed a year ago by Iran and six world powers. But newly extended talks failed to reach agreement last month, and the interim deal was extended.
