Militants blew up two boys' schools in northwest Pakistan on Sunday, the latest in a wave of attacks by Islamist extremists targeting educational institutions, local officials said. No one was hurt in the pre-dawn attacks on the two schools located in the Mohmand tribal region near the Afghan border. Local administration official Maqsood Khan blamed the attack on Taliban militants avenging ongoing military offensives against Islamist insurgents across the northwest. Another tribal administration official, Roshan Khan, said the bomb attacks completely destroyed the two schools. Islamist militants opposed to co-education have destroyed hundreds of schools, mostly for girls, in northwest Pakistan in recent years.
