NAIROBI, Kenya (AP) — Kenya’s election took an ominous turn on Wednesday as violent protests erupted in the capital and elsewhere after opposition leader Raila Odinga alleged fraud, saying hackers used the identity of a murdered official to infiltrate the database of the country’s election commission and manipulate results.

Soon after Odinga spoke on television, angry protesters in slums of Nairobi and the opposition stronghold of Kisumu in the southwest burned tires, set up roadblocks and clashed with police, witnesses said. Kenyan police opened fire on people protesting election results earlier Wednesday in another opposition stronghold, killing one person. The shooting happened in South Mugirango constituency in Kisii county, said Leonard Katana, a regional police commander.
