BAGHDAD — American flags were set on fire yesterday to chants of "no, no for occupation" as followers of an anti-U.S. Shiite cleric marked the sixth anniversary of the Iraq war.

In five other Iraqi cities, supporters of cleric Muqtada al-Sadr either marched or stood in protest after prayers to demand the release of their allies detained at Iraqi and U.S.-run prisons.

The protests came as a suicide bomber in Fallujah killed an Iraqi police officer and five other people, including civilians, in an attempted attack on the home of the local leader of Sunni security volunteers who turned against al-Qaida.

SEARCH DOG SENT FOR TEEN'S BODY

Holloway, from Mountain Brook, Ala., disappeared in May 2005 in the Aruban capital Oranjestad.
