Two students have been killed and three others injured by a 16-year-old who opened fire at a secondary school in California, officials say.
The shooting took place at the Saugus High School in Santa Clarita, north of Los Angeles, minutes before the school day was due to begin.
The male suspect, who was also injured, is now in custody.
Many US schools have implemented active shooter drills in recent years, following a string of attacks.
According to the BBC police found six people suffering from gunshot wounds and transferred them to local hospitals – and the suspect was later identified as one of those injured.
Two victims – a 16-year-old girl and a 14-year-old boy – died of their injuries, he added.
The other victims were two girls aged 15 and 14, and a 14-year-old boy.
