BBC: Libyan rebels have recaptured four more towns and are moving quickly towards Muammar Gaddafi's heartland of Sirte.
They seized the eastern coastal towns of Ras Lanuf, Brega, Uqayla and Bin Jawad after pro-Gaddafi forces withdrew, under pressure from allied air strikes.
The rebels had recaptured the port of Ajdabiya on Saturday.
US, French, British and other allied aircraft started attacking Libyan government troops eight days ago.
The military coalition was assembled after the UN Security Council authorised action to protect civilians.
