The blast destroyed a large portion of the checkpost and completely demolished a nearby house, killing four people, including two children.
Overall, 13 people were killed, including the suicide bomber, six excise and customs department officials, two policemen, two women and two children, a security officer said, adding that 30 sustained injuries.
