The people of Gabon began casting their ballots on August 27, 2016 in a vote to decide whether President Ali Bongo will remain in office or be unseated by a career diplomat and close associate of his late father, who ran the country for 41 years. The election takes place in a climate of persistent social unrest driven in large part by the economic impact of the slump in the price of oil, which has long dominated Gabon's economy. / AFP PHOTO / MARCO LONGARIMARCO LONGARI/AFP/Getty Images
