A former student unleashed a hail of gunfire in a Florida high school on Wednesday, killing at least 17 adults and children, authorities said.
Florida Gov. Rick Scott ordered government flags flown at half-staff through Monday in honor of victims of the shooting at Marjory Stoneman Douglas High School, a public school of some 3,000 students outside Boca Raton.
The school is closed for the rest of the week, Broward County Public Schools Superintendent Robert Runcie said. The district will offer grief counseling to students and their families.
