Under Operation Enduring Freedom, at which place some of the prisoners were sent by the US where the prisoners did not enjoy the protection of international law or the law of their own country or that of the US?

Guantanamo Bay, a US Naval base in Cuba

The US forces made arrests all over the world, often without the knowledge of the government of the persons being arrested, transported these persons across countries and detained them in secret prisons. Some of them were brought to Guantanamo Bay, a US Naval base in Cuba, where the prisoners did not enjoy the protection of international law or the law of their own country or that of the US. Even the UN representatives were not allowed to meet these prisoners.
