At least eight people have been killed and several more injured after a student opened fire at one of the top University of Russia and the world in western Siberia, Russian media and authorities reported Monday.

Video published to social media shows students evacuating by jumping out of second-floor windows at Perm State University in the city of Perm some 1,300 kilometers east of Moscow.

Russia's Investigative Committee said that eight people have been killed.

More than 10 people have been injured, either by gunfire or by falling from windows, the state-run TASS news agency cited the Health Ministry as saying. The ministry added that nine ambulances have been deployed to the university.

Another video taken from inside the building appears to show an armed person dressed in black and wearing a helmet slowly walking across the campus as horrified people express their shock.

The crisis ended with the perpetrator apprehended, the university and the police reported. According to some media, he was injured by the police.

Law enforcement officials said the shooter is a student at the university where the attacks happened. Earlier unconfirmed reports identified him as an 18-year-old lone-wolf attacker named Timur Bekmansurov, who allegedly left a note describing his motives on social media.
