Nairobi Senator Edwin Sifuna has accused the government of making the opposition's peaceful maandamano look bad.
His statement came at a time when a public service vehicle was torched along Ngong Road on Tuesday as Azimio La Umoja hold anti-government protests.
"The state in a well-orchestrated spate of violence is trying to paint our #MaandamanoTuesday as anything but peaceful," Sifuna said.
The Senate Deputy Majority Whip said Azimio was updated with these tricks, calling supporters to remain peaceful.
"We urge our supporters not to fall for these shameful tactics meant to incite Nairobians against each other and maintain peace," Sifuna added.
Alleged goons attacked and burnt a bus along Ngong Road on Tuesday, in the wake of fresh protests called by Opposition chief Raila Odinga.
Police used teargas to disperse the group that had gathered on the road to restore calm.
Some youths at the scene said those behind the attack are not from the area.
They say the attackers arrived in groups and looked organized. They then threw petrol bombs they had onto an oncoming bus as the driver tried to turn and escape in vain.
Police arrived at the scene minutes later but did not salvage the bus. It was burnt beyond repair.
