Modern-day slavery still exists in different forms in Mauritania. According to some estimates, thousands of Mauritanians are still enslaved. A 2012 CNN report, "Slavery's Last Stronghold", by John D. Sutter, describes and documents the ongoing slave-owning cultures. This social discrimination is applied chiefly against the "black Moors" (Haratin) in the northern part of the country, where tribal elites among "white Moors" (''Bidh'an'', Hassaniya-speaking Arabs and Arabized Berbers) hold sway. Slavery practices exist also within the sub-Saharan African ethnic groups of the south.
