A high-school student armed with a rifle barged into a biology classroom on Monday and killed a police officer and a teacher besides taking 20 students hostage in a school in Moscow.
Al the students have been freed and the gunman has now been disarmed and taken to a police car outside school, said the Interior Ministry spokesman Andrei Pilipchuk on state TV.
He added that the gunman is a student of the same school, but of a higher class.
According to a Russian news website, LifeNews, the gunman was an excellent student who staged the shooting to retaliate against a 37-year-old geography teacher Andrew Kirillov, with whom he had an altercation recently.
The disgruntled student entered the school with a small-caliber rifle and a hunting rifle and said, “I need a geography teacher,” the Russian website reported.
Unlike in US, school shootings are not a common incident for Russia.
The incident comes just days before Russia is hosting Winter Olympics at Sochi from Feb 7, re-igniting the fears over the security during the games.
