Black migrants speak of mistreatment by Libyan rebels

Many black Africans have found themselves caught up in the conflict in Libya.

They claim to have been working in Libya for years and were trying to leave the country when they were arrested - accused of being mercenaries.

Nigerians captured by anti Gaddafi forces say they've been beaten, and that their wives--who are being held in a separate jail--have been sexually mistreated by their captures.

The BBC's Jeremy Bowen spoke to a group of Nigerians currently being held by the anti-Gaddafi forces.
