California, police has said that, two adults and a child have been killed in a shooting in a classroom of a primary school in San Bernardino.
The suspect shot and killed his estranged wife, a teacher, and wounded two children who were behind her, one of whom died of his wounds. Police said he then turned the gun on himself.
Police chief Jarrod Burguan described the incident as a suspected murder-suicide attempt.
Authorities said the gunman, named as 53-year-old Cedric Anderson, had gained entry to the school as a visitor and kept his weapon concealed until he opened fire in the classroom where fifteen children with special needs were being taught.
Up to six hundred students were transferred by bus to nearby Cajon High School, where they were later met by their parents.
