A roadside bomb killed three Iraqi soldiers in northeast Iraq on Saturday, and six people were wounded in attacks by insurgents on four of Baghdad's 1,200 polling stations during the country's constitutional referendum, police said. The bomb exploded early Saturday near an Iraqi army and police convoy in an area about 130 kilometers (80 miles) northeast of Baghdad, killing three policemen and wounding three, an officer said. The convoy was on a patrol unrelated to the referendum, the officer said on condition of anonymity as a security precaution in the volatile area. The attacks in Baghdad occurred near four different polling stations, the Associated Press reported. --SP 1233 Local Time 0933 GMT
