The conclusions, while widely expected, were important because they could serve as the trigger for the council to start deliberating on new sanctions meant to punish Tehran for its nuclear intransigence. In Washington, Undersecretary of State Nicholas Burns said he will travel to London on Monday to meet with the United States’ negotiating partners to try to draft a new resolution to sanction Iran. “It is effectively thumbing its nose at the international community,” he said of Iran. Burns said he hopes the United States and other permanent members of the U.N. Security Council, plus Germany, can quickly draft a resolution to “see Iran repudiated again.” He said it was too soon to say what provisions the resolution might contain. In Tehran, the deputy head of Iran’s Atomic Energy Organization, Mohammed Saeedi, ruled out suspending enrichment, saying such demands were against Iran’s “rights, the Nuclear Nonproliferation Treaty and international regulations.” Ali Ashgar Soltanieh, Tehran’s chief delegate to the IAEA, told The Associated Press that sanctions against the Islamic republic only create “more solidarity of the Iranian nation to protect their inalienable rights.” The council issued three demands to Iran on Dec. 23 – freeze uranium enrichment, stop building heavy-water facilities and fully cooperate with the IAEA. It introduced limited sanctions and gave Iran 60 days to comply – a deadline that expired Wednesday.160Want local news?Sign up for the Localist and stay informed Something went wrong.

Security Council ultimatum to freeze uranium enrichment – a possible pathway to nuclear arms – and has instead expanded its program by setting up hundreds of centrifuges, the U.N. nuclear watchdog agency said Thursday. The finding paves the way for new U.N. sanctions. Hours later, the United States said key countries would meet next week to try to develop new U.N. sanctions against Iran. The International Atomic Energy Agency said in a report to the Security Council and its 35-nation board that Tehran also has continued to build a heavy water reactor and related facilities – which, along with enrichment – could help it develop nuclear arms. In addition, the report said Iran ignored a Security Council call to cooperate with the IAEA in its efforts to shed light on suspicious nuclear activities.
