Iran warned Sunday that referring it to the UN Security Council for possible sanctions over its controversial nuclear activities will lead to a no-win situation with "certain consequences." New Foreign Minister Manouchehr Mottaki also told a press conference that Iran plans to organize tenders for building two more nuclear power plants in the Islamic republic. Mottaki reiterated Iran's position that it won't stop uranium reprocessing, rejecting a US-backed European threat that Tehran has about a week to freeze the activities or face referral to the Security Council for possible sanctions. The United States accuses Iran of using its civilian nuclear program as a cover to secretly produce nuclear weapons. Iran has rejected the charges, saying its nuclear program is geared merely toward generating electricity, not a bomb.
