Libya is home to a large minority of black Libyans, many of whom supported Muammar Gaddafi, the former leader, and some who fought on his side against the rebel uprising.

Al Jazeera's Anita McNaught reports from one such town, Tawergha, where remaining members of the community fear for their lives.
