The Guardian reports:

Tension between Libyan rebels and Nato commanders is growing over the military tactics being used to put pressure on Colonel Gaddafi’s forces.

Rebel leaders in Misrata say they are being urged not to launch further pushes against regime troops to the east of the city, and claim they have been told not to cross certain “red lines”, even though they feel prepared for battle.

The frustration on the ground has been heightened by their belief that Gaddafi’s troops are demoralised and depleted after nearly three months of conflict.

While coalition officials insist they have not issued any direct orders not to attack, they concede they are worried about civilians being caught up in further chaotic fighting, and do not want rebel troops being accidentally hit in bombing raids by Nato warplanes. These continued on Monday and Tuesday, when Tripoli experienced what were perhaps the heaviest daylight bombardments by Nato since the air strikes began in March.
