Mauritanian administrative officers empty a ballot box at a polling station in Nouakchott, on June 21, 2014, during the presidential elections. The Islamic Republic of Mauritania is led by Mohamed Ould Abdel Aziz, an ex-general who led a 2008 coup and won election a year later. He is tipped to win Saturday's presidential poll as leading opposition groups have vowed to boycott the ballot. AFP PHOTO / SEYLLOU (Photo credit should read SEYLLOU/AFP/Getty Images)
