Battle for Tripoli

Rebels have seized much of the Libyan capital Tripoli as pressure grows on embattled leader Col Muammar Gaddafi.

News reports indicate that rebels surged into the city from the east, south and west, and a rebel spokesman claimed that as little as 15% of the city remains in the hands of the Gaddafi regime.

The spokesman also said that Gaddafi's son Saif al-Islam has been captured.

Western leaders have welcomed the news of the rebel advance and called on Gaddafi to end his 41-year reign and leave the country.
