Libya unrest: Gaddafi son 'may be in Bani Walid'
A National Transitional Council spokesman has said he believes one of Colonel Gaddafi's sons, Saadi, is still in Bani Walid.
Anti-Gaddafi forces have encountered fierce resistance in their fight to secure the town, one of only four still loyal to the ousted colonel and his forces.
Andrew Harding reports from just outside Bani Walid.
