Afghanistan's Interior Ministry says roadside bomb blasts in southern Helmand province have killed six civilians.
The Interior Ministry said the deaths occurred Saturday in two places after the victims drove over the devices.
Meanwhile, a joint NATO-Afghan security force has killed several Taliban fighters in an operation in the northeast.
NATO says one of the insurgents killed Saturday near Alasay Valley in Kapisa province, outside Kabul, is a suspected Taliban commander.
He is believed to be responsible for violent attacks against Afghan government officials, as well as the joint forces.
Officials say the insurgents are also suspected of imposing strict curfews on the villages in the valley and conducting illegal patrols to enforce Taliban control on local civilians.
Multiple weapons, including a rocket-propelled grenade, were discovered during the operation.
In southern Afghanistan, the British Defense Ministry said Saturday one of its soldiers was killed by a suicide blast.
