ODM leader Raila Odinga is expected to visit Toi market this morning where close to 2000 traders are counting huge loss after fire gutted their structures.
The morning fire on Tuesday destroyed a large section of Toi Market in Kibera, rendering many traders jobless.
The fire reportedly broke out at 3am and by 6am had reduced the busy market to ashes, with property worth millions of shillings lost.
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 with suspicion it would be an arson attack.
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.
