The remarks come as the six powers continue to work on a new draft sanctions resolution, meeting in New York.

May 17 - Iran, Brazil and Turkey sign a nuclear fuel swap agreement. Iran says it has agreed to transfer 1.2 tonnes (2,646 lb) of its low-enriched uranium to Turkey within a month in return for higher-enriched nuclear fuel for a medical research reactor.
