US armed forces head Libya 'stalemate' warning
The most senior US soldier, Admiral Mike Mullen, has said the war in Libya is "moving towards stalemate".
Libyan rebels have been battling Col Gaddafi's troops since February, but have recently made little headway. The US has now authorised the use of armed, unmanned Predator drones over Libya to give "precision capabilities".
But Admiral Mullen said that US and Nato air strikes had destroyed 30-40% of Colonel Gaddafi's ground forces.
