Opposition Orange Democratic Movement supporters in Kenya began three days of protest at the allegedly rigged presidential elections in December.
From early in the morning, riot police were out in force to stop the gatherings which had been banned. More than 600 have died in unrest since the election.
Although the protests were smaller than one earlier this month, crowds gathered in cities across the country.
In the capital, Nairobi, protesters in Kibera slum, where ODM leader Raila Odinga has many supporters, prepared for the police with barricades.
When ODM leaders in the capital tried to reach central Uhuru (Freedom) Park for a rally, police fired tear gas to disperse them and chased them away.
Some protesters felt the effect of teargas. There was also unrest in the port city of Mombasa and at least two were killed in the western town of Kisumu during the clashes.
The protests follow Tuesday's election of a new parliamentary speaker, Kenneth Marende of the ODM, who backed the party's right to hold the protests.
Mr Odinga called for "peaceful people protest". He hopes international mediation and vocal public support for his party will resolve the crisis.
In Eldoret, where 30 were killed after the December polls, thousands gathered in the streets. What started as a peaceful march dissolved into violence.
Many residents and businesses were forced to close. This man told reporters he was packing up from the Nairobi slum of Mathare before the violence escalated.
