Three of Colonel Gaddafi’s sons were today being held by rebels after they swept virtually unopposed into the heart of Tripoli.
As rebel leaders appeared to take control of the city they arrested Gaddafi’s heir apparent Saif al-Islam and put Mohammad under house arrest.
Gaddafi’s third son al-saadi Gaddafi, the former professional footballer, was also arrested alongside Saif in a tourist village in western Tripoli, a rebel spokesman said.
On a night of extraordinary developments in the Libyan capital, the rebels advanced through the city capturing the central Green Square as the regime crumbled.
In a symbolic move the rebels immediately began calling it Martyr’s Square, rejecting the colour so associated with Gaddafi’s despised regime.
Thousands took to the streets to celebrate the rebels’ success, firing guns into the air, chanting loudly and destroying symbols of Gaddafi.
