BAGHDAD - Nine people were killed when a suicide bomber posing as a shepherd attacked police north of Baghdad on Tuesday and at least six civilians died in a spate of shootings by U.S. soldiers, security officials said.
Police at the Diyala province headquarters in Baquba, 65 km (40 miles) north of Baghdad, said they were taken by surprise when the suicide bomber herded several sheep towards a checkpoint before detonating a belt packed with explosives.
"There was nothing suspicious about him because it's an open, agricultural area and it's normal for shepherds to be around here," Diyala police lieutenant Ali Jassim told Reuters.
Jassim said four police and two civilian men were killed in the blast. Another three women were killed when random gunfire broke out in the chaos after the blast.
Ethnically and religiously mixed Diyala has been identified by U.S. commanders as one of the most dangerous areas of Iraq after Sunni Islamist al Qaeda fighters were driven out of their former stronghold in western Anbar province into other areas.
Attacks across Iraq have fallen by 55 percent since a "surge" of 30,000 extra troops became fully deployed in mid-June, part of a security crackdown aimed at averting civil war between majority Shi'ite Muslims and minority Sunni Arabs.
The growing use of neighbourhood police units, organised by mainly Sunni Arab tribal leaders and based on a model pioneered in Anbar last year, has also been credited for drops in Iraqi civilian and U.S. military casualties in the past two months.
With violence falling, U.S. forces have begun gradual drawdowns that will see about 20,000 troops leave by July 2008.
Overall troop levels in Iraq will fall by about 5,000 when a combat brigade pulls out of Diyala next month, although others from the current troop strength of about 162,000 U.S. troops in Iraq will be redeployed to the province.
