“The representatives of the Iran Six in the [International Atomic Energy Agency’s] Board of Governors agreed the resolution at the current meeting. We expect it to be adopted tomorrow,” Lavrov said after talks with EU High Representative for Foreign Affairs and Security Policy Catherine Ashton in Moscow.

Lavrov told journalists that the resolution reflects the Iran Six’s collective approaches.

The Iran Six, comprising Russia, the United States, China, Britain, France and Germany, have been trying since 2003 to convince Iran to halt its uranium enrichment program.

Earlier in the day, IAEA chief Yukiya Amano said the information contained in the agency’s latest report the military dimension of Iran's nuclear program is credible.

Western powers and Israel suspect Iran of seeking to build nuclear weapons. Iran denies this, saying its program is of a civilian nature. Speculation has been building that Israel is considering a preemptive strike on Iran's nuclear facilities.

The IAEA continues to verify the non-diversion of nuclear material declared by Iran under its Safeguards Agreement, Amano said, urging Tehran “to take steps towards the full implementation of its Safeguards Agreement and its other obligations.”

Ashton told reporters: “I believe that dialogue is the best way to achieve the outcome that we all want for the safety and security of the people of Iran, and for the region and beyond.”

She added, however, that the international community should pressure Iran to achieve its goals.

“It’s also the case that the Iranians have obligations that they have signed up to, and they must make sure that they meet those obligations, and that’s why it falls to the international community as well to put the pressure on to make sure those obligations are met,” she said.
