At least a dozen civilians have been killed in two separate incidents of roadside bomb blasts in Afghanistan during the past 24 hours. A family of seven died when their vehicle struck a bomb in Panjwayi district of southern Kandahar province this morning. A spokesman for the provincial governor said all in the car including two young children died in the blast. Another bomb blast Tuesday evening killed five people in western Farah province. A police spokesman said the civilians were traveling in a private van to<br/>neighbouring Ghor province when their vehicle hit the bomb. Eight<br/>others in the van were wounded. Taliban militants are increasingly planting roadside bombs to target security personnel but civilians are bearing the brunt of such blasts.
