An ex-convict stabbed nine people at a Philippines elementary school Friday, killing three, before parents wrestled away his knife and stabbed him to death with it, police said.
The man killed a teacher, a 5th-grader and an elderly man who was among those who tried to grab the attacker's knife, police Superintendent Hado Edding said.
The man first barged into a room at the Talisayan Elementary School in Zamboanga City in the south and fatally stabbed a teacher, Edding told The Associated Press.
He then went to another room, herded 5th grade students into a restroom and stabbed them one by one until the adults were able to stop him.
Four students and two teachers were being treated at Zamboanga's Brent Hospital, including an 11-year-old girl and one teacher in serious condition, said Dr. Raymond Sator, who was contacted by phone.
Edding said the attacker was Fely Mateo, who had served a prison sentence for murder.
He described Mateo as mentally disturbed but it wasn't clear what prompted the attack.
