Libya's rebel fighters have been making advances in the west of the country in their push towards Tripoli.

Dozens of civilians have fled the Libyan capital, saying living conditions in the city have been deteriorating.

They say food and fuel are in short supply and electricity has been erratic.

Many of them they say it is only a matter of time before the government of Muammar Gaddafi falls from within.
