Fourteen people were killed and more than 40 were wounded on Thursday when a bomb exploded in Quetta, Pakistan, near a madrassa. At least three of the victims were children, police said. The target of the bombing was the madrassa, police said, where students and parents had gathered for a graduation. There are several active militant groups in Baluchistan, Pakistan’s biggest but poorest province. Pro-Taliban militants are active in the province, and Sunni Muslims regularly carry out attacks on Baluchistan’s Shiite minority.
