Teenagers are understood to be among at least seven people shot at a US park in what has been described as a "mass casualty" incident.
Miami Fire and Rescue reported at 6.38pm local time on Sunday seven victims had been shot at West Little River Park in 105th Street NW 24 Ave.
The park is overlooked by the Dr. Henry W. Mack/West Little River K- 8 Center school.
A police CSI vehicle was photographed at the scene as investigations continue.
Miami-Dade Police Department director Alfredo Ramirez III said: "My officers are on the scene of another tragic shooting involving juveniles. This type of gun violence has to end. We must work together as a community."
Talk show host Andy Slater tweeted: "At least seven people, including teenagers, were shot at Little River Park in Miami, law enforcement sources tell me."
Miami-Dade Police tweeted "officers are already on the scene", adding: "#MDPD PIO is responding to a scene of a shooting with multiple victims in the area of 10525 NW 25 Avenue."
It is unclear the severity of any injuries or whether any of the victims has died.
