LONDON (Reuters) - Iraqi civilians and soldiers have accused British and U.S. troops of torturing them for information during the war in Iraq, human rights lobby group Amnesty International says.

Amnesty researcher Said Boumedouha said the group had so far interviewed about 20 people who said they were tortured -- mostly by beatings but at least one by electric shock -- after being detained as prisoners of war. Some civilians were held as suspected Iraqi militia fighters.
