Officials say roadside bombs in southern Afghanistan have killed five policemen and an Afghan guard, reported AP.
Local police official Abdul Jabar says a roadside bomb late Thursday in Kandahar's Arghandab district killed five policemen.
Another blast early Friday in the same province killed a private security guard escorting a convoy ferrying supplies for foreign troops.
Niaz Mohammad Sarhadi, the chief of the district where the blast happened, says four other guards were wounded.
Southern Afghanistan is the center of the Taliban-led insurgency. The militants rely heavily on the use of roadside bombs in their attacks against Afghan and foreign troops. The majority of the victims in such attacks have been civilians.
