The United Nations is investigating a woman's allegations that she was raped by three U.N. peacekeepers from Pakistan, a U.N. official said Tuesday. The men claim they paid to have sex. The 23-year-old woman made the report to the police over the weekend, said Damian Onses-Cardona, a spokesman for the 7,400-member U.N. force. The men, whose names were not released, said the woman was a prostitute and they paid to have sex with her, he said. The latest rape allegations come as the United Nations investigates sexual abuse allegations in a handful of countries around the world, most notably in Congo. The three Pakistanis were ordered to return from northern Gonaives, where the incident allegedly occurred, and remain in the capital of Port-au-Prince until the investigation is concluded this week, said Onses-Cardona, who declined to give more details. Calls to police in Gonaives were not immediately returned.
