Hanoi firemen extinguished a fire in the basement of the State Bank of Vietnam on Saturday, nearly three hours after the fire broke out.
At around 8:30am, a guard from the building opposite the bank on Ly Thuong Kiet street, sensed smoke coming out of the basement.
Motorbikes and other assets were quickly evacuated from the three subterranean floors.
Hanoi firemen arrived at the scene in three trucks, 15 minutes after the building was evacuated.
The flames reportedly reached up into the mid-level basement before firemen pumped flame retardant chemicals into the underground blaze.
At around 11am, the fire stopped.
Initial investigations showed that a short circuit in the basement storeroom had caused the fire.
Traffic around the building remained jammed throughout the morning.
