Iran has warned the West it will curb cooperation over its nuclear programme if it is pushed into a corner. Tehran is under mounting international pressure to come clean about its atomic ambitions before talks in Geneva with major powers this week. The US is pushing for stricter sanctions, but Russia is urging restraint fearing they could push Iran to dig in its heals. Foreign Minister Sergey Lavrov earlier met his Iranian counterpart to discuss the issue.The West wants immediate and unfettered access to a newly-declared uranium enrichment facility, but Iran says it will not discuss that at Thursday’s talks in Switzerland. Tehran insists the plant near the city of Qom does not breach international regulations and says it will soon inform tel the UN when its inspectors can visit the site. Tension was also cranked up yesterday when Iran test-fired a long range missile. The US and other western governments condemned the launch, which the White House said was ‘provocative’.
