Flames broke out in a refrigeration repair shop at 335 Le Van Luong Street and worked their way across the entire roof that covers two other businesses.
Fire investigators said it is too early to determine the cause of the blaze. No serious injuries were reported.
The fire, started just before noon, already was burning in the roof over the refrigeration shop when firefighters arrived. Storeowners and passers-by tried to use fire extinguishers to quash the flames without success.
The facade of the three businesses seemed to be the only parts of the structure that still was intact after the blaze was brought under control.
