Islamabad: Pro-Taliban militants blew up a state-run girls' school in the restive Khyber tribal region of northwest Pakistan, injuring three children, officials said on Monday.

The militants detonated a bomb planted at the school in Jamrud area of Khyber Agency on Sunday afternoon. The blast caused extensive damage to the school.     The roof of the school watchman’s house collapsed, injuring his three children.

No group claimed responsibility for the attack though such incidents are usually blamed on the Pakistani Taliban.

Officials said militants had blown up or torched more than 60 schools in Khyber Agency this year.

The Taliban, who oppose the education of girls, have destroyed hundreds of schools in northwest Pakistan over the past four years.
