A gunman with a swastika on his t-shirt killed 13 people, including seven children, and wounded more than 20 at a school in Russia on Monday before committing suicide, investigators said.
The motive for the shooting in Izhevsk, capital of the Udmurtia region about 970km east of Moscow, was unclear.
Russia's Investigative Committee, which handles major crimes, said the gunman was wearing a balaclava and a black teeshirt with Nazi symbols. It said his identity had not yet been established.
The committee said the six adult victims included teachers and security guards. It said 21 people, including 14 children, were wounded.
Tass news agency quoted investigators as saying the attacker was armed with two pistols and a large supply of ammunition.
Russia has seen several school shootings in recent years.
In May 2021, a teenage gunman killed seven children and two adults in the city of Kazan. In April 2022, an armed man killed two children and a teacher at a kindergarten in the central Ulyanovsk region before committing suicide.
