Thousands of people were gathered at a Florida park Saturday to watch drones shining red and green perform a holiday light show when a few of the drones collided and fell into the crowd, officials said,

What was intended to be a dazzling festive spectacle ended in injury to a 7-year-old boy after several drones unexpectedly fell from the sky during a show in Florida on Saturday night, according to CNN affiliate reports.

Adriana Edgerton and Jessica Lumedge told CBS News the injured person was their 7-year-old son, Alezander, and said he needed emergency heart surgery. They told CBS affiliate WKMG that their son was hit in the stomach by one of the drones.
