Nuclear talks between Iran and world powers have resulted in a "broad framework of understanding" but there remains "quite a lot of work to do," Britain's foreign minister said Wednesday as talks stretched into a seventh day.
"I think we have a broad framework of understanding but there are still some key issues that have to be worked through. Some of them are quite detailed and technical so there is still quite a lot of work to do but we are on it now and we'll keep going at it," Philip Hammond told British media in Switzerland.
