MOSCOW (AP) — A gunman killed 17 people, including 11 children, and wounded 24 other people in a school in central Russia on Monday, authorities said.

Russia's Investigative Committee said the shooting took place in a school in Izhevsk, a city about 600 miles east of Moscow in the Udmurtia region. Those wounded included 22 children, the Committee said.

The governor of Udmurtia, Alexander Brechalov, said in a video statement that the gunman shot himself.

The Committee identified the gunman as 34-year-old Artyom Kazantsev, a graduate of the same school, and said he was wearing a black T-shirt bearing “Nazi symbols.” No details about his motives have been released.

The school educates children between grades 1 and 11. It has been evacuated and the area around it has been cordoned off, the governor said.

Izhevsk, a city of 640,000, is located west of the Ural mountains in central Russia.
