"The voice of the people must be heard. Our peaceful protest continues," opposition leader Raila Odinga wrote on Twitter.

The Wednesday-to-Friday demonstrations are the third round of protests that the opposition has called this month.

Several people were reported shot, some possibly fatally, on Wednesday and senior opposition leaders were arrested after demonstrators hurled rocks at police and security forces fired volleys of tear gas.

The Nation newspaper reported that Odinga's Azimio opposition party had called for its supporters to assemble at Huruma grounds, Kangemi grounds and Central Park in the capital Nairobi on Thursday.

A lawyer for the former leader of the Mungiki criminal gang, Maina Njenga, who has been seen at opposition rallies recently and is viewed as a close Odinga ally, said Njenga was among those arrested on Wednesday.
