Rebels target Gaddafi's hometown

Libyan rebel forces are trying to push towards Col Gaddafi's hometown of Sirte, having taken most of Tripoli.



But they have faced fierce resistance from Gaddafi loyalists on the approach to the city, which is still under loyalist control.



There are reports of fresh fighting in Tripoli, which had mostly been quiet overnight.



The rebel government leader Mahmoud Jibril has appealed for urgent aid to avert a humanitarian crisis.



Basic supplies and power are running low - the National Transitional Council (NTC) has said it urgently needs $5bn (£3bn) to prevent further destabilisation.
