Oil prices rose for the first time in two days Friday as tensions escalated over Iran's nuclear ambitions and Federal Reserve Chairman Ben Bernanke said he continued to support a federal lending program that could weaken the dollar. Benchmark crude for November delivery added 13 cents to settle at $66.02 a barrel on the New York Mercantile Exchange. In London, Brent crude rose 29 cents to settle at $65.11 on the ICE Futures exchange. Oil prices slumped most of the week after government reports showed the U.S. continues to sit on a huge petroleum surplus as the U.S. driving season comes to a close. But they rebounded early Friday when President Barrack Obama and the leaders of France and Britain issued a stern warning to Iran, demanding the country come clean on its nuclear program. "Iran is breaking rules that all nations must follows," Obama said at the opening of the G-20 economic summit in Pittsburgh.
