An 8-year-old, a 7-year-old and an adult were shot near Savannah Street SE.
Three bystanders, including two children, were shot in a hail of gunfire in southeast D.C.
An adult and an 8-year-old boy were both shot in the ankle, and a 7-year-old boy was shot in the shoulder. The 7-year-old suffered the most serious injury, but none of the injuries appears to be life-threatening, News4's Darcy Spencer reported.
One of the children was transported by medical helicopter to a hospital. The other victims were transported via ambulance.
D.C. Police Chief Cathy Lanier said that the children were walking with a neighborhood youth camp counselor when the shots were fired. About 30 children were in the line of fire.
"To open fire when there's children in the street is just ridiculous," Lanier said.
One witness told Spencer she heard 11 shots being fired during the incident. Several cars also were struck. Bystanders sought cover in a nearby rental office at an apartment building.
The gunman apparently was chasing and firing at another person, Spencer reported.
Police continue to search for the shooter. D.C. K-9 units and a police helicopter were used in the search.
