Texas high school shooting in the U.S

The attacker, who was arrested and charged with murder, was identified as Dimitrios Pagourtzis, a 17-year-old pupil at Santa Fe High School. He allegedly used a shotgun and a revolver taken from his father, who legally owned the weapons. Most of the dead are students.

Pagourtzis' social media pages showed multiple images of guns. He recently posted a photo wearing a T-shirt reading "Born to Kill" and there were also photos of a long dark jacket with Nazi symbols.

The shooting at Santa Fe High School was the nation's deadliest such attack since the massacre in Florida that gave rise to a campaign by teens for gun control.
