The U.N. nuclear agency estimates that monitoring Iran's compliance with terms of the nuclear deal Tehran reached with six world powers will cost $6 million (4.4 million euros.)

The figure is contained in a confidential report obtained Friday by The Associated Press. It was prepared for a meeting Monday of the U.N. International Atomic Energy Agency's 35-nation governing board, which is expected to approve the IAEA's monitoring role.

The report says the IAEA can save minimal costs by reassigning some staff but most of the funding will have to come from contributions.

The six-month deal is scheduled to be implemented starting Monday and is meant as the first step toward a permanent accord.
