Tunisia - Libya Uprising - Refugee Crisis at the Ras Djir Border Checkpoint

A refugee crisis is looming on the Libyan-Tunisian border as thousands desesperate foreign workers try to escape Libya. Many tens of thousands more are expected to flee west from the violence. About 70,000 refugees had entered Tunisia since the uprising began in Libya and only an estimated 20 percent had been repatriated, the UNHCR team-leader said.
