Al Jazeera has gained access to Bossembele, known by some as "Guantanamo" of the Central African Republic.

It is one of Africa's most secretive 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.

Al Jazeera's Nazanine Moshiri reports from the prison.
