PAKISTAN, Islamabad : Pakistani political party workers, traders and students light candles during a vigil in Islamabad on December 18, 2014, for the children and teachers killed in an attack by Taliban militants on an army-run school in Peshawar. Pakistan is mourning 148 people — mostly children — killed by the Taliban in a school massacre that prompted global revulsion and put the government under new pressure to combat the scourge of militancy.
