A suicide attacker detonated a car bomb near police and Canadian soldiers in southern Afghanistan Saturday, killing three policemen and two civilians, police said. A further five people were hurt in the blast on a road that links the southern city of Kandahar with Herat in the west, local police commander Mohammad Akbar told a foreign news agency. "Initial assessments show that three policemen and two civilians are killed. Four police and a civilian are wounded," Akbar said. There was no immediate claim of responsibility for the blast but it was similar to others by extremist Taliban insurgents, who regularly attack Afghan troops and their international counterparts.
