Two people died after night-long skirmishes between two rival groups within Mathare slums.
The two people were hacked to death with pangas, axes and other crude weapons by a rival gang believed to be Mungiki sect members that confronted them as they marched home from Sunday's Rainbow Alliance rally at Uhuru Park.
The dead were fished out of the filthy Nairobi River by police and the bodies transferred to the City Mortuary awaiting post mortem examination.
Several others were rushed to Kenyatta National Hospital (KNH) by St John's Ambulance personnel who were called to take the injured to hospital.
Twenty-eight-year old welding engineer, Raphael Oyando Odero narrowly escaped death but sustained serious injuries when he met the gang. He sustained deep cuts in the head and arms but was rushed to a clinic by good Samaritans.
Odero said that he was going to the shop when he was confronted by the group which asked him to identify himself. "They suddenly attacked me with pangas, axes, rungus and other crude weapons. I tried to block the blows but they chopped my hands," narrated Odero at the Geomayogo Medical Clinic and Maternity in Mathare Area 4A.
