Internal documents show the US military exported the "brutal interrogation techniques" from Guantanamo prison and applied them to three terror suspects in US jails, civil rights groups said Wednesday.
The so-called "Guantanamo protocols" -- sleep and sensory deprivation, prolonged isolation and death threats -- have been applied to mainland prisons despite attempts by some military personnel to improve harsh conditions, the American Civil Liberties Union (ACLU) and the Allard K. Lowenstein International Human Rights Law Clinic at Yale Law School said in a statement.
The military documents, including regular emails between military officers, were obtained under the Freedom of Information Act, and detail the detention and interrogation at naval prisons in Virginia and South Carolina.
They focus on three "enemy combatants:" two US citizens, Jose Padilla and Yaser Hamdi, and a legal resident, Ali al-Marri.
"Guantanamo was designed as a law-free zone, a place where the government could do whatever it wanted without having to worry about whether it was legal," said Jonathan Freiman, an attorney with the Lowenstein Clinic.
"It didn't take long for that sort of lawlessness to be brought home to our own country."
