One month after human rights defender Mr Biram Dah Abeid was arrested, a peaceful anti-slavery march was violently cracked down. Several activists were severely injured and the wife of Mr. Abeid, Leila Mint Ahmed Khliva, was injured by a grenade. Since Mr. Abeid, president of the ‘Initiative de Résurgence du Mouvement Abolitionniste de Mauritanie’ (IRA) was arrested on 29 April 2012, his whereabouts continue to remain unknown.
