Thats not true mate. They called Hala il Misrati, she surrendered herself, and is now in the custody of the rebels, she confirmed that she wasn't hurt.
Yes, they got Saif el Islam and Saadi el Gedaffi. Mohd el Gedaffi is under siege in his own house, refusing to surrender to the rebels.
The reason none of those ran away was that until yesterday night, there was absolutely no chance of the rebels capturing Tripoli this fast, everybody including the rebels were stunned at the complete lack of resistance at Tripoli. He would have run immediately.
Back to Tripoli news, Khamis another of Gedaffi's sons, is now leading a group of tanks and fighters to liberated areas of Tripoli. Also, there has been several casualties and heavy fighting at the presidential compound in Bab el Aziziya.
