"It is unfortunate that we had to lose lives in Kasarani. Brought together the area leadership, the matatu SACCOS, the security agencies and the Kenya Urban Roads Authority and made sure the situation is normalized. Contractor is on site as we speak and operations are on," Sakaja wrote.

On Friday, Sei appeared to suggest that the statement had come late in the day.

She also took issue with the use of language in Sakaja's statement that described the deaths as unfortunate.

"Senatorial ambulance chasing at its best. Perhaps Mhesh @SakajaJohnson forgot his senatorial oversight role with respect to devolution until WaKenya were killed or harassed or injured in #Kasarani. PS: It's not "unfortunate". It's extra judicial killing," the activist said.

The residents of Kasarani took to the streets for the last four days to protest the poor state of the constituency's roads.

Law enforcement officers from the dreaded General Service Unit (GSU) were deployed to quell the unrest.

A young boy was reportedly shot dead.

There were allegations that the officers employed excessive force as they engaged in running battles with the protesters.
