A video shot by a student and posted on social media shows a SWAT team entering a classroom in a Florida high school after a 19-year-old gunman opened fire with an assault rifle.
The shooting left 17 people killed and more than a dozen injured after a former student of Marjory Stoneman Douglas High School, identified as Nikolas Cruz, walked into the school and opened fire on students and teachers, Broward County Sheriff Scott Israel said.
