What information do we have about the attack?
Mr Minnikhanov reported the deaths of seven children at School No 175, four boys and three girls, as well as a teacher and a female school worker. The children are thought to be eighth graders (aged around 15).
Mr Minnikhanov added that eighteen children and three adults were being treated in hospitals for bullet wounds, fractures, and bruises.
The attack started at 09:20 local time (06:20 GMT), according to a source in the emergency services, according to Russian news agency Tass. Five minutes later, the first signal from the school’s panic button was received.
“Everyone started panicking and saying ‘shut the doors’,” a student who witnessed the attack told the Mediazona news website. “About a minute later the head teacher started yelling: ‘We’re shutting the doors!’
“We got out about 15 minutes later, not out of the windows. I wanted to do that, but the teacher closed the window immediately and said no.”
