Kabul, March 11 (IANS): At least 13 people were killed while 47 wounded in three separate bomb attacks in Afghanistan on Tuesday evening, official sources said.

In one attack, seven civilians and one attacker were killed after a suicide car bombing targeted a police vehicle in Lashkar Gah, provincial capital of southern Helmand province.

"The blast occurred in Bolan locality, a suburban in Lashkar Gah. The attack caused seven civilians and the attacker killed and damaged several vehicles," provincial government spokesperson Omar Zwak told Xinhua.

Four police and 23 civilians were injured in attack that occurred at around 6 p.m., the official added.

The second explosion came 15 minutes later in Pul-e-Khumri, the provincial capital of northern Baghlan province after a roadside bomb was detonated when a police vehicle was passing the road, leaving one woman dead. "About 13 pedestrians and two policemen aboard the vehicle were also wounded," a medical official said.

In southern Uruzgan province, a police officer, two children and a civilian were killed and five passers-by were wounded when a bomb targeted a car in provincial capital of Tirin Kot at around 6:30 p.m., according to a provincial security official.
