A bomb blast in southwestern Pakistan killed two children and injured 16 people on Saturday, police officials said.

Seven policemen were among those injured when the remote-controlled bomb, attached to a motorcycle, detonated near police headquarters in Pishin, the city's senior superintendent of police, Manzoor Buledi, told the media.

"Explosives were planted in a motorcycle which was parked in the area," said police officer Mujeeb-Ur-Rehman, adding that the two children killed were passing through the area when the blast occurred.
