When violence broke out in the western Libyan town of Zawiyah, Bangladeshi migrant worker Mohammed Nienn, 28, was doing a shift as a steelworker. In a hurry to leave, he persuaded his Libyan supervisor to hand back his passport, but not the wages he was due. Then he jumped into a taxi with four other Bangladeshis and headed for the Tunisian border, where a bus eventually took him to Choucha transit camp, 25km from the frontier town of Ras Ajdir. Ten days later, he was still there, waiting for a flight to Dhaka.
