U.S. troops and Iraqi security forces have detained 49 suspected insurgents north of Baghdad, as operations continue to secure the country ahead of January's election.
The U.S. military says the pre-dawn raid Friday was in the town of Duluiyah, in the insurgent-plagued Sunni Triangle north and west of Baghdad.
Meanwhile, in Baghdad, firefighters extinguished a blaze at the city's main oil refinery, which was attacked by saboteurs late Thursday.
Also Friday, near Fallujah, the body of an Iraqi National Guardsman was found with a note warning others against working with U.S.-led forces. Iraq's security forces have been the main target of insurgent violence.
And South Korea's parliament overwhelmingly approved keeping its 3,600 troops in northern Iraq for another year.
