WASHINGTON (AP) — U.S. officials said Monday the United States has taken the first step in its planned expanded fight against Islamic State militants, going to the aid of Iraqi security forces near Baghdad who were being attacked by enemy fighters.

The U.S. Central Command said it conducted a strike Monday in support of the Iraqi forces southwest of Baghdad. There was also an airstrike Sunday near Sinjar in northern Iraq.
