At least three persons were killed following a shooting at an elementary school in Northern California in the US, officials said.

Among the dead are the gunman, who was killed by police, authorities said on Tuesday, the Los Angeles Times reported.

“At this point the suspected shooter is deceased by law enforcement bullets,” Tehama County Assistant Sheriff Phil Johnston told reporters. “I know of at least three deaths.”

Authorities said the shooting occurred around 8 a.m. in Rancho Tehama, near Red Bluff, about 193 km from Sacramento.

Johnston did not have a total number of victims but said that “a number” of students had been medically evacuated from the scene.

“We have about 100 law enforcement personnel in Rancho Tehama right now,” Johnston said.
