At least 14 school children and one teacher in Russia have been injured in a suspected knife attack.
It is claimed two of the injured have been taken to hospital with severe neck injuries, whilst other injuries are less serious.
Initial reports claimed two men in masks entered school property this morning (January 15) in Perm, a city in the east of European Russia.
However later reports suggested the incident started with a fight between two pupils armed with knives.
The incident is said to have caused mass panic at the school, with many allegedly injured as they tried to break up the fight.
The state-run RIA Novosti news agency has been told two suspects have now been detained by authorities.
Some reports suggest the incident was inspired by the Columbine High School massacre, RT said.
According to The Moscow Times, the regional investigative committee has now started a criminal investigation into attempted murder.
