Militants blew up a government official's house in the Kurram region on Sunday, killing him and five other people, local government and security officials said. The attack in the Sadda area of the Lower Kurram region, which killed junior local government official Sarfraz Khan, as well as his son. The pre-dawn attack on Khan's home was not related to sectarian violence in predominantly Sunni Muslim Pakistan, and could be a reaction to an ongoing military crackdown on Taliban militants in the region, officials said. "Explosives were planted near the boundary wall of the house and went off early in the morning, killing six people," local government official Khalid Mumtaz Kundi told media. "It is not related to Moharram, and could be a reaction to the military action," he said, referring to the Islamic calendar's first month.
