According to Reuters, the report was likely to blunt Washington's push for more severe sanctions against Iran. One senior UN official familiar said US efforts to escalate sanctions against Iran would provoke a nationalistic backlash by Iran that would set back the IAEA investigation in Iran. In late October 2007, chief IAEA inspector Olli Heinonen described Iranian cooperation with the IAEA as "good," although much remained to be done. In late October 2007, according to the International Herald Tribune, the head of the IAEA, Mohamed ElBaradei, stated that he had seen "no evidence" of Iran developing nuclear weapons. The IHT quoted ElBaradei as saying "We have information that there has been maybe some studies about possible weaponization. That's why we have said that we cannot give Iran a pass right now, because there is still a lot of question marks. ... But have we seen Iran having the nuclear material that can readily be used into a weapon? No. Have we seen an active weaponization program? No." The IHT report went on to say that "ElBaradei said he was worried about the growing rhetoric from the U.S., which he noted focused on Iran's alleged intentions to build a nuclear weapon rather than evidence the country was actively doing so. If there is actual evidence, ElBaradei said he would welcome seeing it." November 2007 report A IAEA report of 15 November 2007 found that on nine outstanding issues listed in the August 2007 workplan, including experiments on the P-2 centrifuge and work with uranium metals, "Iran's statements are consistent with ... information available to the agency," but it warned that its knowledge of Tehran's present atomic work was shrinking due to Iran's refusal to continue voluntarily implementing the Additional Protocol, as it had done in the past under the October 2003 Tehran agreement and the November 2004 Paris agreement. The only remaining issues were traces of HEU found at one location, and allegations by US intelligence agencies based on a laptop computer allegedly stolen from Iran which reportedly contained nuclear weapons-related designs. The IAEA report also stated that Tehran continues to produce LEU. Iran has declared it has a right to peaceful nuclear technology under the NPT, despite Security Council demands that it cease its nuclear enrichment. On 18 November 2007, Ahmadinejad announced that he intended to consult with Arab nations on a plan, under the auspices of the Gulf Cooperation
