LASHKAR GAH, AFGHANISTAN: A suicide bomber killed seven people and wounded 20 others outside a bank in the capital city of Afghanistan's Helmand province on Saturday, the governor's office said on Saturday.
The bomber detonated an explosives-packed car next to an Afghan army vehicle as soldiers arrived at a bank in Lashkar Gah to collect their pay, the Helmand governor's spokesperson, Omar Zwak, said.
Among the dead were four civilians and three soldiers. Sixteen civilians and four soldiers were wounded, he said.
There was no immediate claim of responsibility but the Taliban have seized large areas of Helmand and have often threatened Lashkar Gah.

Hundreds of international troops are stationed in Helmand as part of the NATO-led effort to train and support Afghan security forces, which have struggled to contain a growing insurgency.
At least one American special forces soldier was wounded in fighting there this week.
To the north of Lashkar Gah, a local official said that an American military air strike killed a number of civilians in a recent bombing in Sangin district.
The allegation has not been independently verified.
