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 believe the girl may have been bullied at school.
There have been several school shootings in Russia in recent years, although Thursday's incident is believed to be the first involving a female shooter.
In 2021, a 19-year-old killed seven children and two adults at a Kazan school.
The following year, 18 people were killed at a school in Udmurtia.
