Back to Africa for another nightmarish penitentiary. The civil wars in Rwanda pitted the ethnic Hutus and Tutsis against each other, and when the Tutsis came out on top, they didn't have too much in the way of mercy for their opponents. Many dissidents were interred in Gitarama, a horrific complex near Kigali. Originally built to hold just 500 men, the cells were packed tight with a staggering 7,000 people after the 1995 genocide. Inmates were forced to stand outside in the yard for hours at a time with no room to move around, and nearly half of them started suffering from gangrene due to the unsanitary conditions. The violent, filthy atmosphere inside Gitarama reduced men to beasts, with frequent fights leading to bloody bites and other injuries that went untreated by staff. Dozens died every day at the prison's peak.
