A woman sorts through a pile of cashew nuts as children look on next to a farm owned by former Guinea Bissau army chief General Antonio Indjai outside Mansoa, Guinea-Bissau, May 8, 2015. Relaxing in flip-flops in a shady corner of his farm near a pile of freshly-raked cashew nuts, the former head of Guinea Bissau's army General Antonio Indjai says he has turned in his weapons and his days as a coup leader are over. For many, Indjai is a symbol of all that went wrong in the former Portuguese colony that is one of Africa's most fragile states. Since 1980, Guinea Bissau has suffered nine coups or attempted coups, including one led by Indjai in 2012 that led to two years of public looting and a surge in drug trafficking.
