(AP Photo/Carolyn Kaster) President Obama and the leaders of France and Britain demanded today that Iran fully disclose its nuclear ambitions "or be held accountable" to an impatient world community. They threatened new sanctions after the disclosure of a secret Iranian nuclear facility. "Iran is breaking rules that all nations must follows," Obama said in the opening moments of the G-20 summit. French President Nicolas Sarkozy said Iran has until December to comply or face sanctions. "This is for peace and stability," he said. British Prime Minister Gordon Brown accused Iran of "serial deception." Earlier, Tehran confirmed reports that it had built a second uranium enrichment plant, which has been hidden from inspectors. Its "size and configuration" do not suggest peaceful purposes, said Obama. Read These Next New York Times ranks the best movies of the 21st century.
