I provdied it in my previous post. Here it is again:
BBC News - 'Cleansed' Libyan town spills its terrible secrets
Ethnic cleansing is defined as the forceable removal of a people based on their race, ethnicity, or religion. The people in Tawahreg cannot return to their homes, they were forced out.
Per the BBC source:
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.
They were specifically targeted because they were black. Whether they had acutally fought for Qadfahi or not was irrevelant to the rebels, they were all deemed to be guilty.
This releates to Syria because the Syrian rebels are modelling themselves on the Libyan rebels. Syria is similar to Libya in that it is tribal based, but with more ethnic and religious minorities. So if Assad falls it is quite possible we could see acts of revenge that amount to war crimes, including ethnic cleansing, by the rebels like what happened in Libya. Thus, it is not off topic.
