PAKISTAN-NORTHWEST-SCHOOL

Pakistani residents hold lighted candles during a ceremony in Karachi on December 16, 2016, as they pay tribute to victims on the second anniversary of an attack on The Army Public School in the northwestern city of Peshawar. Parents of children killed when Taliban gunmen overran a Pakistan school have gathered to mark the second anniversary of the attack, just days after another youngster died from his wounds. More than 150 people -- mostly students -- perished when heavily-armed men raced through the Army Public School in Peshawar on December 16, 2014, firing indiscriminately. / AFP / ASIF HASSAN (Photo credit should read ASIF HASSAN/AFP via Getty Images)
