A picture taken on March 31, 2017 shows West African migrants returning from Niger after fleeing Libya due to armed groups by pickup truck in Agadez, northern Niger, following their failed attempt to reach Europe by crossing the Mediterranean Sea.  Many migrants from sub-Saharan Africa are driven through southern Libya in trucks to the northern coast where they later attempt the perilous Mediterranean crossing to Italy in Europe some 300 kilometres (180 miles) away. People traffickers have exploited the chaos in Libya since the 2011 uprising deposed and killed strongman Moamer Kadhafi to boost their lucrative but deadly trade.  / AFP PHOTO / ISSOUF SANOGO
