President Dmitry Medvedev hardened Russia's stance on Iran's nuclear programme Friday after the US, Britain and France revealed that Tehran possesses a hitherto secret uranium enrichment facility.
As the world powers that negotiate with Iran over its nuclear programme prepared to confront the Teh-ran regime at a meeting on Thursday, Moscow's apparent change of approach will be analysed closely by western diplomats.
The key issue for the US and its allies will be the reaction from Russia and China to the news, amid hopes that the international community will present a united front at next week's meeting in Geneva. Moscow and Beijing have tried to block the west from imposing sanctions on Tehran.
