US ready for Iran talks - if enrichment suspended

Washington remains interested in joining any direct nuclear talks with Iran if it heeds UN Security Council demands, a US envoy said Tuesday, even as Tehran warned that America will regret detaining five Iranian officials in Iraq. Gregory L. Schulte, the chief US delegate to the International Atomic Energy Organization, spoke outside a 35-nation board meeting focusing on Iran's nuclear defiance of the council and against a backdrop of heightened anti-US rhetoric coming out of Tehran over the detentions. The US military has said the five Iranians held in Iraq since January are suspected of links to a network supplying arms to insurgents - an accusation that Iran has denied.
