On Tuesday morning a large section of Toi Market in Kibera was consumed by fire, rendering many traders jobless.
Property worth millions of shillings has been lost in the monstrous fire that reportedly broke out at 3am and by 6am had reduced the busy market to ashes.
Nairobi fire brigade has contained the fire.
The cause of the fire is yet to be established and police are also yet to establish casualties.
Toi market holds thousands of wooden stalls in which traders sell their wares. Traders at the market deal in fresh food and second-hand clothes.
In 2014, a huge fire destroyed a section of the market after a fire started in one of the stalls. Police at the time said preliminary findings indicated the fire was caused by an electric fault.
