The international debate over whether to arm opposition fighters in Syria remains at “an early stage,” Secretary of State Hillary Rodham Clinton said Tuesday, adding that “there’s no plan that we can point to.”

Clinton told the Senate Foreign Relations committee that Syria offers “a more difficult and complicated set of circumstances” than Libya, where NATO and several Arab countries directly intervened, providing supplies and training for opposition forces during the uprising that eventually led to the overthrow and death of Moammar Gaddafi.
