Three people including a middle aged woman died on the spot following a grisly road accident involving a Nissan Matatu and a trailer along the Nairobi-Nakuru highway. During the late Tuesday afternoon accident near KARI farm 10kms from Naivasha town, seven passengers were injured while three are in critical condition. The accident occurred after a trailer that was heading to Nairobi from Nakuru hit a pedestrian before losing control and ramming onto an oncoming matatu. The matatu driver and a female passenger died on the spot. There was a major traffic snarl-up that was worsened by overlapping drivers before traffic police moved in to contain the situation.
