What happened

How grievance turns to violence in a mass shooter's mind April 21, 2026On an otherwise ordinary Thursday, a 14-year-old entered a middle school in the southern city of Kahramanmaras, opening fire on two classrooms, killing eight students and a teacher.

Why it matters

The shocking attack followed another school shooting two days earlier in Siverek in Turkey’s Sanliurfa province, in which the gunman wounded 16 people before killing himself in a showdown with police.

Common ground

While it often seems that such attacks come out of the blue, they are rarely spontaneous.

Perspective signals
