Protests rocked the capital Nairobi and western parts of the country as Kenya's main opposition National Super Alliance (Nasa) supporters reacted to declaration of President Uhuru Kenyatta's re-election in the Tuesday's vote.

Protestors lit bonfires, set up blockades and engaged police in running battles in Siaya, Homa Bay and Migori counties from Friday night, after the electoral commission announced the presidential results, and Saturday.

In Siaya, the body of a man shot by police during the night protest was still lying on the road Saturday morning.

Some roads were still blocked in the morning.

Relatives said the victim, a boda boda operator, was shot by a police officer during the protest.

"We received information that my brother was killed from the chaos that escalated after the police engaged youths in running battles," said John Okumbe, the victim’s brother.

"We prevented the police from picking the body as we believe they will conceal evidence," said a resident, Mr Kevin Otieno.

In Homa Bay and Migori there were reports that three people were injured during the protests.

In Nairobi, gunshots rent the air and police used teargas to disperse protestors, who had lit bonfires in Mathare, Kibera, Kawangware, Korogosho and Dandora slums on Friday night, shortly after the announcement.

A police helicopter overflew the affected areas for the better part of the night.

There was an uneasy calm on Saturday morning.

In Kisumu, in the west of the country, police were deployed to man roads after protestors took to the streets on Friday night.

Police engaged the protesters in running battles late into the night and used teargas to disperse them.

Gunshots

Most youths were blowing vuvuzelas and whistles while others wailed.

Gunshots could still be heard after midnight but the situation calmed towards dawn.

At the Kenyan coast, in Mombasa and Kilifi -opposition strongholds- most shops remained closed Saturday as police intensified patrols in the areas.
