A roadside bomb ripped through a vehicle in Afghanistan’s Kandahar province killing at least six people on Tuesday.

According to police spokesman Qasim Afghan, the vehicle was travelling from Kandahar’s Dand district to the provincial capital when the bomb detonated near the car killing everyone inside.

Four children — two girls and two boys — are among those killed in the blast.

All the victims were members of one family, Police officer Jamal Nasir BarikzaI said.

No group has claimed responsibility for the attack yet.

Haji Abdullah, governor of Dand district, said the bomb was placed by the Taliban on a road frequently used by foreign and Afghan forces.

The incident in Kandahar comes just a week after at least six people were killed and dozens wounded in an explosion in Kabul.
