Iran and six world powers on Tuesday appeared likely to extend talks on Tehran's nuclear program beyond a July 20 deadline, while Washington said the Islamic Republic must cut its capacity to make nuclear fuel to secure a deal to end sanctions.

Iran and the six nations are trying to bridge differences in negotiating positions over a deal intended to end a decade-long dispute over Tehran's nuclear programme, which Western nations fear may be aimed at developing a nuclear weapons capability. Iran says it is for peaceful purposes.
