Aitizaz Hasan, 15, was late for school on Monday and as a punishment wasn't allowed to attend assembly.
Hasan and two schoolmates were standing outside the Government High School Ibrahimzai in Hangu, a town in Khyber Pakhtunkhwa province, when they saw a man approach. One of Hasan's friends spotted a detonator on the man; the schoolmates ran inside. But, as the newspaper wrote, "Aitizaz stood his ground and got hold of the bomber, who then detonated his vest."
