Videos Posted From Inside and Around The Russian School Massacre Shows The HORROR The Children Went Through That Day

Seven children and two adults have been killed in a shooting at a school in the Russian city of Kazan, officials say.

Twenty-one other people, mostly children, were injured. A 19-year-old suspect was detained.

The attack happened in the capital of the Republic of Tatarstan, 820km (510 miles) east of Moscow.

Eighteen children and three adults were being treated in hospitals for gunshot wounds, fractures and bruising, Mr Minnikhanov added.

The attack began at about 09:20 local time (06:20 GMT), a source in the emergency services told Russian news agency Tass. The first signal from a panic button at the school was sent five minutes later.

"Everyone started panicking and saying 'shut the doors," a student who witnessed the attack told the Mediazona news website. "About a minute later the headteacher 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."

Footage shared on social media shows some children jumping from windows to escape as well as injured people being evacuated. Russian TV reported that two of the children had died after jumping from a second-floor window.
