The rebels who ring the camp suddenly open fire. Then they race into the camp, shouting “gabbour, gabbour” — Arabic for whore — and haul away young women, residents say.

“You should be here in the evening, when they come in firing their guns and taking people,” one woman from Nigeria said Wednesday as she recounted the nightly raids on the camp. “They don’t use condoms, they use whatever they can find,” she said, pointing to a discarded plastic bag in a pile of trash.

As she spoke, other women standing nearby nodded in agreement.

There is no way to know how many women have been raped here, where hundreds of Africans have settled in and around the boats of a marina. No one keeps statistics in the camp, and foreign aid workers say they are prohibited from discussing the allegations on the record. International Red Cross representatives say only that they have spoken to rebel leaders about “security concerns.”
