Files obtained by the website Wikileaks have revealed that the US believed many of those held at Guantanamo Bay were innocent
At least 150 people were revealed to be innocent Afghans or Pakistanis - including drivers, farmers and chefs - rounded up during intelligence gathering operations in the aftermath of 9/11.
The detainees were then held for years owing to mistaken identity or because they were in the wrong place at the wrong time, the memos say. In many cases, US commanders concluded there was "no reason recorded for transfer".
Sami al-Hajj, a Sudanese cameraman for al-Jazeera, was held for six years, partly so he could be questioned about the Arabic news network
Abdul Badr Mannan, an author, was considered high risk, but his files states US officials may have been "misled" by the Pakistani security services
Mukhibullo Abdukarimovich Umarov, a Tajik man, was arrested in Karachi in 2002 and spent almost two years at Guantanamo before being released - his assessment says the reasons for detaining him were "undetermined"
Haji Faiz Mohammed was arrested in Afghanistan aged 70 and is described as having senile dementia - his file states there is "no reason on record" for being transferred
Naqib Ullah, aged about 14 when he was arrested, spent a year in Guantanamo but his file states he had been kidnapped by the Taliban and presented no threat to the US.
