While Libyan leader Muammar Gaddafi's regime continues to hang on to power, resistance is growing, particularly in cities in the east of the country. A town 30 minutes away from Tripoli - the capital and Gaddafi's stronghold - has fallen to the opposition. 

As numerous units of Gaddafi's armed forces have switched allegiance, questions are being raised about the embattled leader's military support.

Meanwhile, footage has emerged on the internet of Gaddafi's son, Saif al-Islam, with a rifle in his hand, exhorting people to fight for his father and pledging to give them weapons.
