Libya protests: Col Gaddafi under mounting pressure
Libyan leader Colonel Muammar Gaddafi is under huge pressure, amid spiralling unrest throughout the country.
Several senior officials - including the justice minister - have reportedly resigned after security forces fired on protesters in the capital Tripoli.
And in a TV address, Col Gaddafi's son Saif al-Islam conceded that protesters had taken control of the eastern cities of al-Bayda and Benghazi.
He warned of civil war and vowed to "fight to the last bullet".
