Two people, both adults, have been killed, and two children are critically injured, following a shooting, believed to have been a murder-suicide, at a primary school in the US state of California.
The victims, a female teacher and the suspect, were both adults, police Lt Mike Madden said.
Police chief Jarrod Burguan described the incident as a suspected “murder-suicide” attempt.
The shooting happened at 10:30 local time (17:30 GMT).
Mr Burguan tweeted shortly after the incident that the suspect was “down” and there was “no further threat”. The school was immediately evacuated.
The shooting took place in a classroom of North Park Elementary School in San Bernardino county, 60 miles (96km) east of Los Angeles.
Police said they believe that the teacher was known to the gunman.
It is thought that the two injured children, who were airlifted to hospital, were not targeted by the killer.
