Killers attack a school today. Today I have gone to a hospital for doing a exam. After I have gone to work. When I arrived at work, I saw a violent attack against students at an school on TV. Two young boys invaded the school and killed 10 people, staffs and students. After one of boy killed his uncle in a cars shop. When the police officers arrived at school the killers killed himselves with a gun. They were studied at school in the past and one suffered bulying for his classmate. They used guns, crossbows, arrows and axes during the attack. It's a crazy youth.
