At least eight people have been killed in a school shooting in the Russian city of Kazan, officials said Tuesday.
One of the victims was a teacher and the other seven were students at Kazan's School No. 175, the press service of the head of the republic of Tatarstan told state media.
Video posted by Telegram news channels shows children jumping out of the school's windows to the sounds of gunfire. The state-run RIA Novosti news agency reported that two more students died after jumping from a third-floor window, citing a source in the emergency services, but these deaths have not been confirmed.
Officers detained the shooter. Russian media outlets identified him as School No. 175 graduate Ilnaz Galyaviyev, 19, and reported that he announced his plans to commit the shooting on social media.
The regional Interior Ministry has denied that there were any accomplices after initial reports said that officers had killed a second shooter.
