Authorities said at least three people are dead following a shooting at an elementary school in Northern California on Tuesday morning.
Among the dead are the gunman, who was killed by police, authorities said.
"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 120 miles northwest of 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 with multiple, multiple scenes," Johnston said.
"I know that we have (airlifted) a number of students" he told reporters. "I know that we have children that were attending school in a safe location at this time."
Officials said the Rancho Tehama area remains on lockdown.
"We have had an active shooter incident at Rancho Tehama Elementary this morning," read a statement from the Corning Union Elementary School District website. "There are confirmed injuries. We are cooperating with law enforcement during this investigation but do not have specific details at this time."
