A teenage girl has shot and killed a fellow pupil in a school in western Russia before shooting herself. The attack happened in the city of Bryansk, close to the Ukrainian and Belarusian borders, on Thursday morning.
Five people were injured in the shooting, one of them seriously, Russian authorities said.
The gun used by the girl was registered in her father’s name, a parliamentarian said.
Police were called to Gymnasium No 5 in Bryansk at about 09:15 local time (06:15 GMT) on Thursday.
Alexey Kuznetsov, Russia’s deputy health minister, said one victim was undergoing surgery.
Police say they believe the 14-year-old girl may have been involved in a conflict with classmates.
Students, teachers and parents at the school have been offered psychological support, journalists were told by the local authorities.
Mr Khinshtein added that one of the reasons the tragedy occurred was the “neglectful attitude” towards the storage of the gun.
