Iraq's largest Sunni party says it has suspended "all official contacts" with American military
personnel and civilians after the killing of a man near Fallujah, the Associated Press reported.
The Iraqi Islamic Party says in a statement Saturday that U.S. and Iraqi soldiers killed a senior member of the party in his bed and arrested five others during a raid on Friday.
The statement says the raid had "hidden political goals" after the party forged tribal alliances with other political blocs.
A U.S. military statement says Iraqi soldiers arrested a wanted insurgent in an operation that killed an armed man.
The move is an indication of rising political tensions in the Anbar ahead of provincial elections, due to be held by the end of January.
