The US military said Thursday it killed four Iranian-backed Shiite fighters and detained five others during operations north of Baghdad while a suspected member of al-Qaeda in Iraq was killed in Baghdad, dpa reported.
US troops came under attack during an operation in Rashidiyah, north of Baghdad, to detain a "special groups criminal" suspected of receiving money and weapons from Iran to launch attacks on coalition forces, the military said.
