Ex-prisoners speak of abuses in secret Bossembele prison

Bossembele, known by some as "Guantanamo" of the Central African Republic, is one of Africa's most secret prisons, where ousted president Francois Bozize allegedly had his opponents jailed and tortured for years. A alliance of rebel groups known as Seleka captured Bossembele and freed all prisoners as they moved against Bozize in March 2013. Al Jazeera gained access to the prison in April 2013.
