QUETTA: The security forces sealed a seminary in Quetta’s Eastern Bypass area on Sunday and took into custody around 100 Afghan students. The arrested students were studying in the seminary without any valid documents. “A search operation was conducted inside the seminary and the Afghan students were arrested under Foreigners Act,” said a security official. The arrested students were later handed over to various police stations for further questioning. The security forces also seized suspicious literature and other material from the seminary. The Afghan nationals who were illegally staying at the seminary would be repatriated to Afghanistan, the security official said. Security forces have intensified operation in the aftermath of Quetta carnage, which left more than 70 people, most of them lawyers, dead.
