A pupil killed at least three people and injured five when he opened fire on his classmates at a high school in northern Mexico on Wednesday, an official said.
The boy fired at fellow pupils in the Northeastern College in the city of Monterrey before trying unsuccessfully to kill himself, civil protection official Oscar Aboytes told AFP.
Local television footage showed ambulances and police outside the college, named the Colegio Americano del Noreste.
However, Nuevo Leon state security spokesman Aldo Fasci said the middle-school student shot only two people – a teacher and another student – before turning the gun on himself.
Fasci said the wounded all had vital signs but were in extremely serious condition. He added the motive was still under investigation.
The website of the American School of the Northeast says it offers bilingual education for students from preschool through ninth grade.
It was unclear how the student – reported locally to be aged only 12 – got the gun into the school. Mexico had once had a program that checked book bags at school entrances, but in many places it has fallen into disuse
