Iraqi MPs okayed a $400-million (270 million euro) compensation deal on Saturday for Americans who say they were mistreated by executed dictator Saddam Hussein's regime during the 1990-1991 Gulf War.
A total of 226 lawmakers were in the Council of Representatives' main chamber, with a majority approving the agreement, which was originally signed between Baghdad and Washington in September.
MPs loyal to radical anti-US cleric Moqtada al-Sadr walked out of parliament when the issue was put to a vote, however.
