Four people died on Thursday when the vehicle they were travelling in veered off the road at Mitheru, Tharaka Nithi county.
The vehicle, reportedly from Nairobi, was heading to Kipkona in Igembe Central, Meru, where the passengers were to attend the burial of a business associate from Nairobi.
According to eyewitnesses the driver of the vehicle was trying to avoid a head-on collision with a vehicle that was overtaking when the driver presumably lost control, veered off the road and landed in a seasonal river.
