A bomb attached to a motorcycle went off near a car stop in Spin Boldak district of Taliban's former strong hold Kandahar province on Saturday morning, killing five people including the saboteur, wounding eight others, police said.
"It was around 9:30 a.m. local time (0500 GMT) when a bomb in the motorbike blew up prematurely, killing the culprit and four other civilians," Jawad Ahmad, a police spokesman at Spin Boldak, told Xinhua.
Ahmad added that eight other civilians including three women and two children were wounded in the incident.
He blamed "the enemy of Afghanistan", a term used against Taliban militants, for the incident, saying so far it is not clear who was the target of the bomber.
This not the first time that civilians became the victims of militant's crucial tactics of suicide and roadside bombings, as four Afghan farmers were killed Thursday when their tractor struck a roadside bomb in Shah Walikot of the Kandahar province.
Taliban militants, who staged a comeback three year ago from their traditional hot bed south of Afghanistan, have vowed to speed up their assaults against Afghan and international troops stationed in the post -Taliban country.
