Iran envoy dismisses tougher terms for atom fuel swap

Iran's envoy to the UN nuclear agency dismissed on Tuesday a US suggestion that Tehran should agree to tougher conditions than those it rejected last year for a possible nuclear fuel swap.

Western diplomats say economic sanctions are beginning to have an impact on Iran, and it may be possible to revive the fuel exchange plan if it also accepts broader talks they hope will lead to Tehran agreeing to curb its enrichment drive. (Reuters)
