On “African mercenaries” in Libya:

Are the men we see pictured here perpetrators of state-sponsored violence, are they victims of racism, or is it possible that both of these things may be true at the same time? Are they being attacked in retaliation or in the course of a battle, or are they taken for mercenaries simply on the basis of their skin color? Is this just one more instance of non-citizens falling victim to a conflict that is not their own?
