Q&A - Is there a 'right' to enrich uranium? Iran says yes, U.S. no

GENEVA (Reuters) - Disagreement over whether Iran has the right under international law to enrich uranium goes to the heart of the decade-old dispute over its nuclear programme and has held up diplomacy to end the standoff.

Iranian officials made clear on the third day of talks in Geneva on Friday that the Islamic state's "right" to enrich uranium must be part of any interim deal aimed at curbing its atomic activity in exchange for some sanctions relief.
