NOUAKCHOTT: A Mauritanian anti-slavery organization accused the police of injuring, arresting and using tear gas against several of its members Thursday, as they demonstrated in Nouakchott for the release of two imprisoned activists. More than 100 members of the Initiative for the Resurgence of the Abolitionist Movement in Mauritania (IRA) protested in the capital for the release of the organization’s leader and another employee, the NGO’s spokesman, Hammady Ould Lehbouss, told AFP. “Twenty-three of the protesters were arrested and six were injured during clashes with police, who were using batons and large amounts of tear gas,” he said. Slavery was officially abolished in Mauritania in 1981 and since 2007 those found guilty of involvement in the trade face up to ten years in prison. According to several NGOs, however, slavery still exists in the country.
