Documents released by WikiLeaks reveal that the US knew many of the detainees at Guantánamo were innocent or low-level operatives.
The documents, published in American and European newspapers, provide an analysis of all 780 people who have ever been imprisoned at Guantanamo.
The analysis shows that 220 of them were considered dangerous terrorists, but that among the other prisoners there were 150 innocent Afghans and Pakistanis.
380 people were ordinary "dusters", low-level operatives.
Now, about 180 people are imprisoned in the Guantanamo base.
The documents also reveal alleged plans and conspiracies against Britain and the USA.
The alleged plots, revealed by the interrogation, include claims of nuclear weapons hidden in Europe, which would be detonated if al-Qaeda leader Osama Bin Laden was captured.
Other plots uncovered include plans to put cyanide in the air conditioning systems of public buildings in the US, as well as Al Qaeda's attempts to recruit workers at London's Heathrow Airport.
Wrong place at the wrong time
Among the 150 innocent prisoners were Afghans and Pakistanis, who were drivers, farmers and cooks, and were caught during manic operations by security services in war-torn areas.
They were kept in prison for years because they were in the wrong place at the wrong time, or because their identities were switched, the notes said.
US commanders came to the conclusion that "there was no reason to close
In many cases, US commanders came to the conclusion that "there was no reason to close."
The Pentagon commented on these allegations as "unfortunate" and described the analysis as taken out of context and greatly outdated.
The White House, however, says that "Obama remains committed to the planned closure of Guantanamo."
US President Barack Obama said in January 2009 that he would close the base in Guantanamo within the next year.
However, in March of this year, he announced that he had lifted a two-year ban on military trials of Guantanamo detainees.
The White House, however, says that "Obama remains committed to the planned closure of Guantánamo."
