Iran, 6 powers seek to narrow differences at nuke talks but substantial differences remain
{{#rendered}} {{/rendered}}Iran and six world powers are hoping to narrow differences at a new round of nuclear talks, less than three months before an informal July deadline for a deal.
Negotiations resumed Tuesday, and substantial differences remain.
The scope of Iran's uranium enrichment program is the toughest issue. Iran argues it needs robust enrichment capacities to make low-enriched reactor fuel. The U.S, Britain, France and Germany want significant cuts to limit any potential effort to turn the program into making high-enriched material for nuclear arms. Russia and China are somewhere in the middle.
{{#rendered}} {{/rendered}}Iran denies any interest in atomic arms. It is seeking an end to economic sanctions in return for any nuclear concessions.
A first-step deal now in effect curbed some Iranian nuclear activities in return for limited sanctions relief.
