A masked 18 year old who was carrying a hammer and a chainsaw burst into a busy shopping mall in Minsk, Belarus, decapitating one woman and seriously injuring another.
An onlooker told the Belarus news website Onliner: “He lashed out at the nearest person and cut off her head. When he took out a chainsaw, shoppers first thought it was some kind of game. Then he cut one woman badly with the chainsaw and hit her with a hammer. She died. He also attacked others.”
Hundreds of people were in the shopping center at the time of the attack. Police say the assailant was detained at the time of the attack.
