As wealthier nations send boats and planes to rescue their citizens from the violence in Libya, a new refugee crisis is taking shape on the outskirts of Tripoli, where thousands of migrant workers from sub-Saharan Africa have been trapped with scant food and water, no international aid and little hope of escape.
The migrants — many of them illegal immigrants from Ghana and Nigeriawho have long constituted an impoverished underclass in Libya — live amid piles of garbage, sleep in makeshift tents of blankets strung from fences and trees, and breathe fumes from a trench of excrement dividing their camp from the parking lot of Tripoli’s airport.
Sub-Saharan Africans make up a vast majority of the estimated 1.5 million illegal immigrants among Libya’s population of 6.5 million, according to the International Organization for Migration. Many were desperately poor people made even more so by investments of up to $1,000 each to pay smugglers to bring them across Libya’s southern border for a chance at better work in its oil economy.

Unfortunately, the poverty and lack of legal status of many of these people is compounded by racism.
Despite Colonel Qaddafi’s brotherly pan-African rhetoric, racial xenophobia is common here. Many Libyans, ethnically Arab, look down on Chinese, Bangladeshis and darker-skinned Africans, in that order. Many African refugees here and in the camps on the Tunisian border say Libyans often addressed them as “abd,” or slave.
