It was not a good night for a few members of Kibera slum on Tuesday.
Quite a number of residents were forced to sleep out in the cold after a fire broke out at the Gatwekera area.
Sources said the fire began from one house and rapidly spread to the next. The cause is, however, yet to be known.
Police have now launched investigations to provide more details on the inferno.
The government is now being asked to help out by the affected so that they can rebuild their houses.
There were no injuries reported but property of an unknown amount was destroyed.
