At least three people have died in Kenya after police fired gunshots and tear gas in a stadium where crowds of mourners had gathered to see the body of former Prime Minister Raila Odinga.

Prominent rights group Vocal Africa told the BBC that three bodies of those killed in the chaos had been taken to the city's main mortuary. Local media has reported that a fourth person also died as officers sought to disperse the surging crowds.

It is not yet clear whether the police used live ammunition or rubber bullets in the arena, located in the capital, Nairobi. Vocal Africa said those who died had sustained gunshot wounds.

A BBC reporter at the scene also saw men in civilian clothing beating protesters with batons.
