Bush says threat of World War III if Iran goes nuclear

U.S. President George W. Bush warned on Wednesday a nuclear-armed Iran could lead to World War III as he tried to shore up international opposition to Tehran amid Russian scepticism over its nuclear ambitions.

Bush was speaking a day after Russian President Vladimir Putin, who has resisted Western pressure to toughen his stance over Iran's nuclear program, made clear on a visit to Tehran that Russia would not accept any military action against Iran.
