A number of students have taken to social media to pay tribute to Tahira Qazi, the school principal. The messages are a sign of the respect and affection students felt for Qazi. Muhammad Ahmed called her a brave lady, mother, and teacher in a tweet. Rahim Khan tweeted saying his heart was bleeding. According to the BBC, a witness quoted in local media said Qazi helped many students to safety, even calling parents to come pick up their children. Two years ago, Qazi was awarded Principal of the Year for "achieving excellence and showing professional exuberance in her duty," according to the BBC.

I born free and I will live free. I am Pashtoon."
