Pro-Azimio supporters in Nairobi on Monday took to the streets accompanying leader Raila Odinga.
As the convoy snaked through Ngong road, it was met with teargas with officers trying to stop it.
Earlier, the officers threw teargas at the convoy at Kawangware, prompting the protestors to pelt stones at them.
The police then boarded their vehicle, and they rushed to safety.
As at 4:57pm, the convoy has made a stop at Kibra.
