Major roads in the city were on Thursday afternoon gridlocked after an accident along Kenyatta Avenue involving six vehicles.

The six cars were involved in an accident within the Central Business District of the city almost brought movement by cars to a standstill.

An eyewitness recounted that a PSV bus rammed onto stationary vehicles waiting for the traffic lights to give them a nod to proceed.

"I don't know if the brakes failed or what happened but it rammed onto a stationary vehicle which in turn hit the other until the sixth one," Peter Thiong'o explained.

A number of vehicles were badly damaged in the accident. No causalities have been reported yet. Police rushed to the scene to help clear the road to avoid a buildup of traffic on the busy street.

On Wednesday, yet another accident happened along on Ngong road, where a speeding matatu overturned after its driver lost control.

In a video shared on Twitter by Ma3Route, passengers can be seen jumping out of the overturned bus. No one was fatally injured during the accident.

These accidents have raised a red flag with MPs taking to task Interior CS Fred Matiang'i and the Inspector General of Police Joseph Boinnet to explain the increasing number of accidents on Kenyan roads over the last one month.

The two are, however, yet to appear before National Assembly's Transport committee.
