A former student injured at least 16 people Tuesday after opening fire with a shotgun inside a high schoolin Turkeybefore turning the weapon on himself, officials said.

The 18-year-old who targeted the vocational high school in Siverek, located in southeastern Turkey, took his own life with the shotgun after he was \"cornered by police,\" Gov. Hasan Sildak said.

Video taken at the scene showed students sprinting out of a building as law enforcement and first responders arrived.
