TEHRAN, January 31 (RIA Novosti) - Iran ratcheted up the tension around its nuclear programs further Tuesday, when the country's top negotiator said the referral of the country's "nuclear file" to the UN Security Council would mark the final chapter in diplomatic efforts to end the escalating crisis.

"We regard any mention or report on Iran in the UN Security Council as the end to diplomacy," said Ali Larijani, the secretary of the country's Supreme National Security Council. "For Europeans and the International Atomic Energy Agency Board of Governors, it will mean an unsuccessful and bad solution to the issue."

The IAEA, the UN's nuclear watchdog, is due to discuss the Islamic Republic's nuclear research during an emergency session on February 2-3.

However, Larijani said Iran was not giving up talks with the trio of European nations handling the issue - Britain, France and Germany - and saw the negotiations with them as the only way out of the current crisis.

Representatives of three countries, as well as China, the United States and Germany met in London Monday to discuss Iran's nuclear programs. They decided that the UN Security Council would be kept informed about Iran's "nuclear file," but no action would be taken until March after a regular session of the IAEA, the Russian Foreign Ministry said Tuesday.

Tensions around Iran escalated after it abandoned a two-year moratorium on research into uranium enrichment January 10. Some members of the international community, led by the U.S., fear that Tehran could use the technology to produce weapons-grade material, as well as nuclear reactor fuel.
