MOSCOW - A gunman opened fire on a university campus in central Russia and killed six people before being detained, investigators said, in the country's second mass shooting this year to target students.
Video on social media showed students throwing belongings from the windows of university buildings in the city of Perm, around 1,300 kilometres east of Moscow, before jumping to flee the shooter.
The Investigative Committee, which probes major crimes in Russia, initially said eight people were killed but later revised the number of deaths to six.
It said 28 people were being treated after the attack at Perm State National Research University.
"Some of them have been hospitalised with injuries of varying severity," it said in a statement.
It said the gunman, later identified as a student at the university, carried out the shooting with a hunting rifle he purchased earlier this year.

"During his arrest, he put up resistance and was wounded, after which he was taken to a medical facility," the statement said.
The health ministry, in comments cited by Russian news agencies, said 19 among the wounded were being treated for gunshots.
State media broadcast amateur footage reportedly taken during the attack showing an individual dressed in black tactical clothing, including a helmet, carrying a weapon and walking through the campus.
Video from outside the university showed distressed students fleeing the campus and making phone calls to friends and family behind a cordon of police wearing helmets and body armour.
President Vladimir Putin had been notified of the shooting, the Kremlin said, and ministers had been ordered to travel to Perm to coordinate assistance for the victims.
"The president expresses sincere condolences to those who have lost family and loved ones as a result of this incident," Putin's spokesman Dmitry Peskov told reporters.
School shootings have been relatively unusual in Russia due to tight security at education facilities and because it is difficult to buy firearms.
