At least three people were also wounded in the attack, including the 17-year-old daughter of the school’s headmaster, who suffered serious injuries. The school, behind a high white wall with few external markings, was cordoned off by police, who then escorted other children outside. One officer held a distraught girl, her face in her hands. A mother and son were seen walking away from the site, their faces visibly pained. Within an hour, search helicopters could be seen flying over the city hunting for the gunman.
