AP: Top diplomats from the world's leading economies are ramping up pressure on Iran to prove its nuclear ambitions are peaceful, renewing calls for the country to be hit with new international sanctions if it fails to comply.

AFP: US Secretary of State Hillary Clinton has said China will play a role in international efforts to pen sanctions against Iran at the United Nations, and that Beijing recognizes the threat of Iran's nuclear program.

Reuters: Foreign ministers from the Group of Eight leading industrial nations will call on the international community to take "appropriate and strong steps" to show its resolve over Iran's nuclear activities.

PA: Shadow defence secretary Liam Fox has warned of the threat of a nuclear-armed Iran and called for stronger sanctions against the country.

AP: Iran's nuclear program is of "critical concern" and will top the agenda when foreign ministers from the Group of Eight nations meet Monday to discuss global security, Canada's foreign minister said.

The Times: The White House said yesterday that it was increasingly confident of winning approval for a new round of sanctions against Iran — as a report emerged suggesting that Tehran is building two more atomic enrichment sites.

New York Times: Six months after the revelation of a secret nuclear enrichment site in Iran, international inspectors and Western intelligence agencies say they suspect that Tehran is preparing to build more sites in defiance of United Nations demands.

AP: Imposing more sanctions on Iran over its nuclear program is not the best option, but it cannot be excluded, Russian President Dmitry Medvedev said Saturday.
