A Kazakh teenager wearing a sinister-looking plastic mask wounded three schoolmates with an axe on Monday at a school in the city of Petropavlovsk in northern Kazakhstan, a police spokesperson said.
Police have detained the student, whose name has not been disclosed. They said two students had been hospitalised and were in a stable condition. A third was released after treatment.
The teenager "jumped into the hallway and started swinging his axe at students", local news website Petropavlovsk News cited an eyewitness as saying.
