In 2002, former US president George W Bush ordered the Guantanamo Bay Detention Camp to be used as a military prison, following the 9/11 attacks, with the aim of detaining prisoners around the globe accused of engaging in terrorism.
Tunisian men who spent years as prisoners at Guantanamo Bay are still not totally free. They have been facing continual harassment from the authorities.
Prisoners at Guantanamo Bay describe harsh treatment, forced feeding and torture.
But two men who came back to Tunisia in 2011 now say they'd rather be prisoners again.
