Three children and a teacher killed in US school shooting

A 16-year-old has shot dead three children and a teacher at a primary school in the US state of Oregon before he was killed by a bystander, police say. The suspect, who has not been named, forced his way into Silver Rail Elementary School on Thursday afternoon by shooting at locked doors. The teenager was shot dead by a community member who "pursued him into the school and engaged him".

Today's Justin Webb hears more from Michael Kohn, a reporter with local newspaper the Bulletin.
