Christina Aguilera 'used to keep terror suspects awake'

INTERROGATION techniques at Guantanamo Bay, including playing Christina Aguilera's music to keep terror suspects awake, have been highlighted in a report.

The first documented log of methods used by the US military to extract information from detainees details a range of techniques that range from a satirical puppet show to making a suspect growl at pictures of terrorists.

The 84-page document, obtained by Time magazine, concerns the interrogation of Mohammed al Qahtani, the so-called 20th hijacker - an alleged acquaintance of Osama bin Laden and an intended participant in the September 11 attacks.

The often hour-by-hour log spans a period of 50 days from November 2002 to January 2003, during which time 16 of 19 additional interrogation techniques were approved by US Defence Secretary Donald Rumsfeld for use on specific detainees.

They included isolation for up to 30 days, removal of clothing, exploiting individual phobias and "mild, non-injurious physical contact." Such methods were later revoked.

The quizzing of al-Qahtani often started at midnight, Time magazine reports. He was woken up by having water dripped on his head or Aguilera's music played.

At one point he was forced to watch a satirical puppet show concerning his involvement with al-Qaida.

An interrogation booth is decorated with pictures of September 11 victims, American flags and red lights, the magazine claims.

The US national anthem was played while al-Qahtani was forced to stand. After one all night session, he was reportedly allowed to sleep for four hours from 7am.

After being subjected to a drill known as Invasion of Space by a Female, he said he would tell the truth "to get out of here" and explained how he met bin Laden. In return, he was given a blanket and an air conditioner was turned off at his request.
