A student opened fire on Friday in a high school cafeteria north of Seattle, killing at least one person and shooting several others in the head, the New York Post quoted officials as saying.
The gunman also died in the attack.
Students in the cafeteria said the gunman stared at the students as he shot them. They described a chaotic scene at Marysville Pilchuck High School, as panicked students ran for safety.
The shooter was a student at the school 30 miles north of Seattle, but Marysville Police Commander Robb Lamoureux said he could not provide more information on the gunman or his motive.
Lamoureux said he did not know if the shooter died of a self-inflicted wound.
Four students were taken to Providence Everett medical center, said hospital spokeswoman Heidi Amrine. Three were in “very critical” condition. It was not immediately clear if the person who died was one of those students.
