Provincial police chief said Selaab Khan was leaving his house when a bomb hidden inside a drainage system was remotely detonated. Khan blamed Taliban militants, who have been expanding their presence in the province, for the attack. He said the militants had tried to kill him two other times in the past two months but their plots were unsuccessful.
