Washington: The US Senate has passed an amendment banning torture with interrogation techniques like rectal feeding and waterboarding, media reported on Wednesday. The bilateral vote was 78-21.

"We must continue to insist that the methods we employ in this fight for peace and freedom must always, always, be as right and honourable as the goals and ideals we fight for," Republican Sen. John McCain, chairman of the Senate Armed Services Committee and author of the amendment, said.
