Civil rights organisation Touche pas à ma nationalité TPMN (in English: Do not interfere with my citizenship) has called for a large march on September 27, 2012 in the capital Nouakchott to commemorate the passing of anti-racism activist Lamine Mangane. Mangane was killed a year ago by authorities in the town of Maghama during protests against a census that marginalized black citizens of Mauritania.
