President Enrique Peña Nieto regretted the shooting at the private school in the northern Mexican city of Monterrey on Wednesday morning.
“As a parent and as a president, I regret so much what happened at a school in Monterrey this morning” he wrote on Twitter.
“I share the pain and dismay of the families and the school community,” the president added.
This morning, a 15-year-old boy suffering from depression injured three students and a teacher and then he shot himself at the Colegio Americano del Noroeste.
