Libya: 'Cleansed' Libyan town spills its terrible secrets

The 30,000 people living in a town in northern Libya have been driven out of their homes, in what appears to have been an act of revenge for their role in the three-month siege of the city of Misrata. So what really happened in the town of Tawergha, are the accusations of brutality against the town's residents fair and what does it say about hopes for national unity? In the middle of August, between the end of the siege and the killing of Gaddafi, Misratan forces drove out everyone living in Tawergha, a town of 30,000 people. Human rights groups have described this as an act of revenge and collective punishment possibly amounting to a crime against humanity.
