U.S. Education Secretary Arne Duncan says a stabbing spree at a Pennsylvania high school is a tragedy and serves as a reminder that children and staff deserve to work and learn in a safe environment.
In a statement, Duncan said he is saddened and his thoughts go out to the victims at Franklin Regional High School.
He says when families send their children to school each day, they expect their children to return home safely.
Twenty people were injured after a 16-year-old with two knives went on a stabbing and slashing spree near Pittsburgh. Among those injured was a school police officer.
Duncan said the government will seek to assist and support students, school staff and the local community.
