PARKLAND, Fla. (AP) — A shooting at a Florida high school Wednesday sent students rushing out into the streets as SWAT team members swarmed in and locked down the building. Ambulances converged on the scene as emergency workers appeared to be treating possibly wounded people on the sidewalks.

Television footage showed police putting a person in the back of a police car outside the high school.

Television footage showed police in olive fatigues, with weapons drawn, entering the Marjory Stoneman Douglas High School, then dozens of children frantically running and walking quickly out. A police officer waved the students on, urging them to quickly evacuate the school.

Some students exited the building in single-file rows with hands raised overhead to show they carried no weapons. Others held onto other students as they made their way out past helmeted police in camouflage with weapons drawn.

Emergency medical personnel pulled stretchers from the backs of ambulances as police cars surrounded the parking lot. At least one person was seen being wheeled to the ambulance on a gurney. It wasn’t immediately clear how many people were wounded.

Parent John Obin says his son, a freshman at the South Florida high school where the shooting erupted, says his child was in class when he heard several shots. The father says his son advised that teachers quickly rushed students out of the school. He adds the boy told his father that he walked by two people on the ground motionless — and apparently dead — as students rushed outside.
