US President Barack Obama has admitted that his country tortured people in the wake of the September 11 terrorist attacks.
Speaking at a news conference, Obama said the White House turned over a declassified report to the Senate on Friday about the techniques that shows the agency went too far in interrogations.
"We did a whole lot of things that were right, but we tortured some folks. We did some things that were contrary to our values," he said.
The US leader added the techniques were used because the United States was afraid more attacks were imminent.
He said: "It's important for us not to feel too sanctimonious in retrospect about the tough job that those folks had. A lot of those folks were working hard under enormous pressure and are real patriots."
