A gang, led by two teenagers, has been charged with murdering 20 people in a series of racist killings over eight months, the Investigative Committee said Monday.

Charges have been brought against nine people aged 17 to 22, including a young woman, aged 22, who recorded one attack, committee spokesman Vladimir Markin said.

"She videotaped the first crime committed by the group. The wounded person survived at the time," Markin said in a statement.

"Lone citizens of non-Slavic appearance were chosen as victims. The assailants attempted to cause grave bodily harm in the shortest possible period of time," he said. "Investigators … accuse the members of the group of 20 cases of murder and 12 attempted murders."

The accused have not yet been tried.
