Any decision to impose a no-fly zone over Libya should be made by the UN and not by Washington, US Secretary of State Hillary Clinton has said.
Mrs Clinton said it was important such a move came from the Libyan people, rather than being a US-led effort.
Calls for military intervention are growing as pro-Gaddafi forces bombard areas held by Libyan rebels.
Meanwhile, Col Gaddafi has made a defiant speech on Libyan TV, labelling rebels and opposition leaders traitors.
Addressing a room full of cheering supporters he again claimed that the rebels had been brainwashed by al-Qaeda.
