At least three school children were among the five people killed in a blast that hit a police van in Pakistan on Friday.
The incident, which also injured 12 others, took place in the Mastung district of the southwestern Balochistan province, police said.
"Five people, including a policeman and three schoolchildren, were martyred in the blast," Mastung district police chief Miandad Umrani told the local daily Dawn.
An explosive, placed on a motorcycle, was detonated remotely near a police van at the Civil Hospital Chowk, it added.
