Watchdog warns of nuclear 'stalemate' with Iran

The UN nuclear watchdog is locked in a “stalemate” with Iran over the country’s suspect nuclear programme, the agency’s chief said today, pressing Tehran to answer lingering questions about its atomic ambitions.

Flashing fresh defiance, Iranian President Mahmoud Ahmadinejad said his government will neither halt uranium enrichment nor negotiate over its nuclear rights, although it’s ready to sit and talk with world powers over unspecified “global concerns.”
