Traders at Gikomba market are counting losses after an early morning fire razed down their property.
Several structures at the cereals and mitumba sections of the market have been destroyed by the inferno.
Reports indicate that the fire started at around 2am on Thursday.
So far, no casualties have been reported but property whose value could not immediately be established was lost.
Firefighters were on the ground battling the inferno as traders were rummaging through the charred iron sheets, half-burnt pieces of timber and ash searching for anything that been spared by the fire.
Earlier this year another fire was reported at the market. Property of unknown value was destroyed and City Hall commenced investigations into the matter.
The several fire incidents at the popular market have caused severe damage over the years, sometimes leading to fatalities and injuries.
