Five British hostages who were kidnapped in Baghdad more than a year ago are alive and Iraqi authorities know where they are being held, Iraq's most senior security official told the BBC on Saturday. He said: "We have a very good, strong intelligence telling us they are alive and we roughly know the area where they are. "But we don't want to be aggressive in our approach, not to risk their lives." The computer expert has been named as Peter Moore, from the eastern English city of Lincoln, who was working for US management consultancy Bearing Point.
