Libya's National Transitional Council fighters detained scores of men accused of fighting for the ousted leader Muammar Gaddafi, who was killed on Thursday (October 20).
Libya's new leaders overran Sirte, the last bastion of his long rule, sparking wild celebrations that eight months of war may finally be over.
NTC fighters said they were transferring the fighters to Misrata.
One vehicle was herding at least 11 Africans. As it drove past a person in the crowd hurled a water bottle at the back of the car.
Throughout the uprising against Gaddafi's 42-year rule, his opponents have accused Gaddafi of hiring fighters from neighbouring countries like Nigeria, Niger, Chad, Mali and Sudan.
That has led to fears of mistreatment of blacks now that the former rebels are in charge.
