Nato air strikes 'hit rebel lines'

Libyan rebels have claimed that Nato air strikes hit their fighters on the front lines and touched off a retreat from the outskirts of the key oil port of Brega.

Several militiamen fleeing back toward rebel-held Ajdabiya in eastern Libya said they saw several of their tanks destroyed by apparent Nato bombing runs. Dozens of vehicles were seen racing from the front lines today, including ambulances and rebel vehicles outfitted with weapons.
