The Virginia Beach Fire Department says seven people were injured in a flash fire at an indoor shooting range.

Battalion Chief Leon Dextradeur says two of the injured are in critical condition with burns to their faces and smoke inhalation. Four people with less serious injuries also were taken to hospitals, and one declined to go to the hospital.

The fire started about 1:30 p.m. Sunday at A&P Arms' Lynnhaven Shooting Range. Dextradeur says there are three shooting ranges in the facility. An explosion at the end of range three started a flash fire that spread quickly toward people at the other end.

The cause of the fire has not been determined.
