One more person has passed away after sustaining injuries during the Thursday night Embakasi fire, bringing the official death toll to three.

Initially, two people were confirmed dead in the explosive fire incident that occurred in Embakasi's Mradi area. The deaths were reported at Nairobi West Hospital.

Several injured persons have since been transported to various hospitals for treatment with the following breakdown: Kenyatta Hospital received 21, Mama Lucy 160, Mbagathi Hospital 19 and Komarock Modern Hospital 14.

This comes after Nairobi Governor Johnson Sakaja announced the exemption of medical fees for persons affected by the destructive fire that occurred in Embakasi on Thursday night.

In a statement on Friday, Sakaja, while sympathising with the affected, said the exemption of medical fees applies exclusively to public county hospitals.

"Currently, all County Health and Medical teams are also managing the situation and also working hand in hand with the County Disaster and Risk management teams who continue to provide the necessary support to the victims of the fire incident," said Sakaja. 

"The County Government has also waived all medical fees at the County facilities attending to the injured and bereaved. We have also mobilised relief items, in conjunction with other agencies, to ensure the comfort of all those affected."

Police say that a lorry loaded with gas cylinders at a suspected illegal station, exploded igniting the huge fire which spread to other buildings.

Police DIG Douglas Kanja says that investigations to determine the cause of the fire have commenced.

One person has been arrested in connection to the incident.
