They are killing black people in Libya. They are killing them in the street, they are killing them in hospitals, they are killing them in transit camps, they are killing them in their houses.
They are not killing any old African. They are killing black Africans, the dark, sub-Saharan Africans. Skin tone, the darkness of one's skin, has become for many blacks in Libya the difference between prison and freedom, death and life.
The rebels who gunned for the toppling of the dictator Muammar Gaddafi have for the past six months been killing anyone who looks dark. Given that there are between a million and two million black Africans in Libya, a slow and under-reported massacre is unfolding in that country.
