According to a Facebook post from the city, a few homes in the area of Hawkins Avenue and McNeill Road have been evacuated as a caution.
Beyond the immediate area of the gas leak and fire, there appeared to be no danger to surrounding residents.
Dominion Energy said the gas leak was secured at 5 p.m.
The leak apparently happened when workers unaffiliated with Dominion struck a gas line.
Repair work is underway.
The area is closed to traffic. Residents are asked to avoid the area.
No injuries were reported.
