>> Kenya's presidential rerun tainted by violence on Thursday, forcing voting to be delayed for two days in four areas. All opposition strongholds in the country's west where the election commission said voting had been hampered by quote, security challenges. Reuters Catherine Harold is in Nairobi.>> At least two protesters were killed in the west of the country where youths lit fires, blocked roads and prevented polling stations from opening.
Police fought back using tear gas and live bullets.>> Earlier residents of a slum neighborhood in the capital firebombed a church designated as a polling station. Even MPs from Kenya's ruling party and the opposition exchanged blows on live television once the polls closed.
These crowds have heeded opposition leader Raila Odinga's call for a voter boycott.
Scenes like this had been feared since August's annulled election where some 50 people were killed in the chaotic aftermath. Odinga has refused to take part in the second attempt over failings to replace election officials. It will likely hand a tainted victory to incumbent President Uhuru Kenyatta who cast his vote early in the day.
And while polling stations did open in much of the country, there are fears if some counties fail to hold elections, it could trigger legal challenges to the result.
