Amnesty International is an international organisation of volunteers who campaign for human rights. This organisation brings out independent reports on the violation of human rights all over the world. The organisation collected information on the condition of the prisoners in Guantanamo Bay and reported that
(a) The prisoners were being tortured in ways that violated the US laws.
(b) They were being denied the treatment that even prisoners of war must get as per international treaties.
(c) Many prisoners had tried protesting against these conditions by going on a hunger strike.
(d) Prisoners were not released even after they were officially declared not guilty.
Thus, Amnesty International helped drawing people's attention to human rights abuses. Even an independent inquiry by the UN supported these findings. The UN Secretary General said the prison in Guantanamo Bay should be closed down.
