Libyan rebels backed by allied air raids say they have seized control of the frontline oil town of Ajdabiya from Colonel Muammar Gaddafi's forces.
Insurgents have been celebrating amid the ruins of tanks and artillery pieces left behind after air strikes.
Gaddafi loyalists seized the town last week as they advanced east to quell an uprising now in its fifth week.
Saturday's breakthrough came after a seventh night of bombardment by allies enforcing a UN-mandated no-fly zone.
British RAF Tornado aircraft have been firing Brimstone guided missiles at Gaddafi forces in recent days around Ajdabiya, a town of about 100,000 people.
The BBC's Ben Brown, in Ajdabiya, says those strikes seemed to be even heavier overnight.
Gaddafi 'promotes everyone'
He counted about 20 Libyan government tanks, armoured vehicles and artillery pieces which have been either abandoned or destroyed at the eastern gate of the town.
There is even more wrecked weaponry at the western gate and lots of bodies of Gaddafi fighters, our correspondent has been told.
