A shooter opened fire at a Florida high school on Wednesday, killing multiple people and sending hundreds of students fleeing into the streets before being taken into custody by law enforcement, authorities said.
Shortly before students were to be dismissed for the day, the sound of gunfire ripped through the air at Marjory Douglas Stoneman high school, Broward County school officials said on Twitter, adding that multiple people had been injured in the incident.
The exact amount of those who have been killed is not known.
The high school is a sprawling complex set on a tract in the South Florida community of Parkland, about 45 miles (70 kilometres) north of downtown Miami.
The school had just over 3,100 students in the 2016-2017 academic year, according to the National Center for Education Statistics.
