Reports from Libya say that hundreds of rebels have swept into the capital Tripoli, advancing towards the city centre. The rebels moved in a convoy of about 100 vehicles after capturing a military barrack and freeing prisoners from a jail, about 16 miles west of the capital. Residents poured into the streets to greet the rebels chanting and waving flags. Video pictures from the city apparently shows the rebels celebrating on Green Square. They met very little resistance from government troops once they entered the capital. Green Square has been the site of night rallies by Gaddafi supporters throughout the uprising. The rebels leadership says that Colonel Gaddafi's son Saif al-Islam, has been captured. However, there is no independent confirmation. Col Muammar Gaddafi has vowed again to defeat the rebels. He is believed to still have thousands of armed followers in the capital but there are reports that a number of them have been surrendering to the rebels. Libyan Information Minister Moussa Ibrahim said fighting in Tripoli since noon yesterday has left 1,300 people dead and 5,000 wounded.
