At least 20 people have been injured in a south Florida high school shooting, local law enforcement says. Police said they were responding to an incident at Marjory Stoneman Douglas High School, in Parkland, Florida, around 3:15 p.m. ET. Florida Sen. Bill Nelson (D) told Fox News that there are "many deaths." The gunman is reportedly in custody, although the scene is still active.
About 3,000 students attend the school, which is described as being in "an affluent Fort Lauderdale suburb," The New York Times writes.
