Mauritania reporting wins online award

A CNN investigation into modern day slavery in Mauritania has won Best Feature at the annual Online Journalism Awards.

Slavery's Last Stronghold” followed the stories of slaves and slave owners in Mauritania, the last country in the world to abolish slavery but where it is thought between 10% and 20% of the population still live in servitude.

Spending nearly a year to gain entry into the country and conducting many of their interviews at night and in covert locations, CNN writer John Sutter and digital content producer Edythe McNamee went to great lengths to uncover the tragedy of slavery across generations. The project was published as CNN's first digital magazine, combining  video, text, photography and interactive components.

The 2012 Online Journalism Awards were presented in San Francisco on September 22. The awards, which began in 2000, celebrate innovation in digital journalism around the world.
