EDGEWATER, Md. -- Anne Arundel County fire officials say seven people were injured Monday after an explosion and fire on a boat in the South River near Edgewater, Md.
Lt. Jack Beall tells WTOP most of the victims are children.
It happened about noon Monday at the Oak Grove Marina. Fire Department Division Chief Keith Swindle says the 32-foot pleasure boat had just refueled when the engine stalled. He said while someone was trying to restart the engine, an explosion and flash fire occurred.
Beall says two 9-year-olds, a girl and a boy, were both taken to the burn center at Johns Hopkins Bayview with serious but not life-threatening injuries.
A 13-year-old girl was taken by ambulance to Johns Hopkins with non-life-threatening injuries.
Four more people, a 9-year-old boy, a 12-year-old girl, a 13-year-old girl and a 31-year-old woman were taken to Anne Arundel Medical Center with non-life-threatening injuries.
The Department of Natural Resources is investigating the explosion.
