An al Qaeda-led group said on Sunday it was holding "crusader" soldiers after a clash with a patrol in Baghdad on Saturday.
U.S. troops backed by helicopters have been searching for three American soldiers who went missing in an al Qaeda stronghold near Baghdad after an ambush that killed four other U.S. soldiers and an Iraqi army interpreter.
"We will provide the full details of this blessed operation as soon as they are available," said the self-styled Islamic State in Iraq in a statement posted on the Internet.
