Nine students and one teacher have died after a 17-year old student armed with shotgun and a pistol opened fire on a Texas high school in Santa Fe.
The gunman, identified by authorities as Dimitrios Pagourtzis, reportedly opened fire in an art class at Santa Fe High School just before 8am.
Explosive devices were also found in the school and nearby, according to Texas Governor Greg Abbott.
The accused is being held on capital murder charges, facing the possibility of a death sentence.
Mr Abbott labelled the attack as “one of the most heinous attacks that we’ve ever seen in the history of Texas schools”.
He also said that there were no clear signs that the student had been planning an attack.
“Here, the red flag warnings were either non-existent or very imperceptible,” Mr Abbott said.
The shotgun and .38 calibre handgun were taken from the suspect’s father, who owned them legally, according to Mr Abbott.
Students were evacuated to hide behind an auto store across the street from the school.
