Nine people were shot late Tuesday during a neighborhood July Fourth celebration in Washington, D.C., the Metropolitan Police Department said.
The incident occurred in a residential community about 5 miles from the center of Washington. All of the victims had non-life-threatening injuries, police said.
Fire and EMS transported some of the victims to area hospitals while others sought their own treatment, police said.
Two of the nine people shot were children, ages 9 and 17.
Police said they were looking for the driver of a dark-colored SUV.
"As it drove through the street, it stopped and it fired shots in the direction of some of our residents that were outside just celebrating the Fourth of July," said Assistant Chief Leslie Parsons. "It appears that the shooting was targeted towards those residents and victims that were struck."

According to the Gun Violence Archive, there have been 346 mass shootings so far this year.
