Four dead as Kenyan security forces fire on crowds mourning Raila Odinga

Thousands gather in Nairobi to pay respects to veteran opposition leader, prompting chaotic scenes at stadium

Four people have been killed in Kenya's capital, Nairobi, after security forces fired shots and teargas to disperse huge crowds at a stadium where the body of the opposition leader Raila Odinga was lying in state.

Odinga, a major figure in Kenyan politics for decades who was once a political prisoner and ran unsuccessfully for president five times, died on Wednesday aged 80 in India, where he had been receiving medical treatment.
