A teacher has died and two pupils are injured after a shooting in a primary school classroom.
North Park Elementary in San Bernardino, California is on lockdown with pupils evacuated to a nearby high school, fire officials said.
Police chief Jarrod Burguan said two adults died from gunshot wounds in a suspected ‘murder suicide’, while another two people are wounded and have been airlifted to hospital.
They are believed to be pupils who were in the classroom.
Photos from the scene show children being led away hand in hand, while parents were informed of a shooting at the school.
One young student, reunited with her mother, told local NBC News affiliate KNBC-TV that Monday’s ordeal left her ‘super scared.’
Anxious parents interviewed on camera said they had been given no information from the school other than where their children were being taken.
All children were bused to a nearby high school and university to make sure each was accounted for. Parents were asked to show ID before being reunited with their children.
Names and ages of the victims have not been released. The school teaches children aged from five to 12.
CBS Los Angeles reported that two adults were found dead in the classroom. One was the teacher and the other the shooter.
Local police chief Jarrod Burguan tweeted: ‘We believe this to be a murder suicide. Happened in a classroom. Two students have been transported to the hospital.
‘Students at the school are being taking to Cajon High School for safety.’
The shooter is believed to have turned the gun on themselves.
‘We do believe the threat is down,’ police said.
The city of San Bernadino is still recovering from a previous mass shooting, when Syed Farook and his wife Tashfeen Malik gunned down 14 people at a Christmas party in 2015.
