KABUL, Afghanistan (AP) - A local official says a roadside bomb attack targeting the car of a district police chief has killed three police officers in southern Afghanistan.
Provincial government spokesman Muhammed Jan Rasolyar says the police chief was not in the vehicle Thursday when it was hit by the blast in the Shinkai district of Zabul province.
Afghan and NATO troops are pushing into the traditional heartland of the insurgency in southern Afghanistan.
They have managed to secure pockets of territory but the insurgents are also carrying out daily bomb attacks and assassination attempts.
There has also been a surge in insurgent activity in northern Afghanistan, traditionally considered more peaceful.
