RT @GavinLeeBBC Interesting insight from Ian Pannell on the plight of black African migrants caught in Tripoli. bbc.in/pb16iA #Libya
A BBC investigation has found allegations of abuse against African migrant workers in Libya by fighters allied to the new interim authorities.
Hundreds of men have been imprisoned, accused of being mercenaries for Col Muammar Gaddafi, and there are claims that homes have been ransacked and looted, and women and girls have been beaten and raped.
It was a visit the Nigerian family had been dreading.
They had been hiding in their tiny slum home in a Tripoli suburb since Col Gaddafi had been swept from power, fearing the knock at the door. Earlier this month 20 rebel fighters came, demanding to be let in, shouting "murtazaka".
It is the word every black African in Libya knows too well. Murtazaka is Arabic for "mercenary", the armed men allegedly employed by the former regime to carry out some of the worst excesses of the conflict.
The fighters forced their way into the Nigerian family's home. They beat the couple living there. They stole their possessions and money, abducted the father of the house and turned on his 16-year-old daughter. She told us what happened:
"A group of armed men came to our house. They started knocking, they came in saying 'murtazaka'. They locked my mother inside a toilet. Six of them raped me. They took our belongings and money. My father tried to stop them but they hit him and carried him away."
That was nearly three weeks ago and she has not seen or heard of her father since.
Violent campaignloyalists and African mercenaries accused of working for Col Gaddafi.
Evidence has emerged in a series of interviews that suggests that some engaged in a violent campaign of abuse and intimidation against the black immigrant community in Tripoli.
Hundreds of men have been arrested with little or no evidence, homes have been pillaged and people beaten up. Most victims are too afraid to be identified but they contacted the BBC to air their grievances.
One man showed us around another home that had been ransacked. A thick iron bar in the corner of the dark room had been used to beat the men and the women there as the rebels made off with their money and few possessions.
He told us he was glad when Col Gaddafi was overthrown, expecting a better life. Instead he and hundreds of others black Africans have become victims, a soft target.
"This is the African continent, I am an African, this is my land. Is it because of my colour, because I am a black man? We don't have a voice. Who would you to turn to?"
On the outskirts of the city we were invited to film a truck-load of men from Niger who had just been picked up. They too were accused of being mercenaries while being made to chant anti-Gaddafi slogans by leering fighters before being put to work hauling boxes of documents and weapons found in the woods.
