The blaze which was concentrated in Gatwekera area of the slum left no casualties its wake.
Kilimani OCPD Peter Katam said fire engines were unable to put out the fire due to extremely narrow feeder roads that provide the sole access to that area of the slum.
“I appeal to area residents to widen the roads to enable easy passage of fire engines in case of incidences such as this one,” he said.
He attributed the fire to an electrical fault.
Kibera residents has over the years borne the brunt of heavy fires that fire officials have been unable to assist due to overcrowded housing.
Several people have lost their lives in one of the biggest slums in Africa.
