VIENNA (Reuters) - Iran will convert more of its higher-grade enriched uranium into reactor fuel under an extended nuclear deal with world powers, making the material less suitable for building atomic bombs, a diplomatic source and a U.S. think-tank said on Monday.
Iran and the United States, France, Germany, Britain, China, and Russia failed to meet a Nov. 24 deadline for resolving their dispute over Tehran's nuclear programme. They gave themselves until the end of June for further negotiations.
