US interrogators in Baghdad are using heavy metal songs to break Iraqi captives.
Officials say subjecting prisoners to long sessions of the “culturally offensive” music encourages them to talk.
The interrogators’ favourite tracks include Metallica’s Enter Sandman and the Drowning Pool song Bodies, from the Vin Diesel action film XXX.
The Metallica song repeatedly makes the warning: “Sleep with one eye open, gripping your pillow tight.”
Sergeant Mark Hadsell told Newsweek magazine: “These people haven’t heard heavy metal before. They can’t take it.”
