This Walrus blog post offers another take on the situation there, a somewhat more reserved perspective from many other articles about the electoral violence. At the same time, there's no doubt that serious problems are going on. Hundreds of people killed, tens of thousands fleeing from their homes, places burning, of course this is terrible.
The post tries to say that inspite of these problems, the country is not falling apart or being consumed by violence and barbarity, as much as certain parts may be. I have a sad feeling though that in reality, the sheer amount of tragedy and suffering in Africa means there's a high threshold for true disaster and what's going on in Kenya now maybe isn't there yet.

This BBC article gives a good commentary on the ethnic tensions apparent in the Kenya crisis. It's important to understand that these tensions aren't necessarily products of pure ethnic hatred or prejudice but exacerbated and exploited by political leaders. Thus when one leader or governing regime favors its own ethnic group by giving land and high-status jobs, then consequently other groups will feel very resentful.

Major violence has broken out in the past few weeks in Kenya over election result disputes, resulting in lots of deaths, injuries and people fleeing their homes. All this mainly stems from overwhelming anger by the opposition and its supporters over the election results which they believe contained significant vote-tampering. The incumbent, President Mwai Kibaki won by a very small margin of 230,000 out of a total of 10 million.
However, it is unfortunate that this great anger and violence that has broken out is strongly based on ethnic tensions. This ethnic tension is a result of continued corruption and patronism during Kibaki's rule in which his fellow Kikuyu were perceived to have benefited whilst many other Kenyans have suffered from poverty and unemployment.
The incumbent party is mainly Kikuyu-supported whilst the opposition has their support mainly based on other, smaller tribes such as the Luo.

This goes to show that ethnic-based tensions and conflicts are still apparent in Africa. Even more disturbing though is the fact that this has taken place in a country considered one of Africa's more stable and even prosperous nations. Ethnic-based politics and tensions have been around since independence as Kenya's first leader Jomo Kenyatta favored his fellow Kikuyus. His successor Daniel arap Moi was a member of another group, the Kalenjin and they were rewarded accordingly during his reign. As the current President Kibaki is also a Kikuyu, many Kikuyu have become the victims of violence and resentment.

Nevertheless it's hard to understand exactly why ethnic violence has broken out when in previous years there has been relative peace and coexistence between the different groups of Kenya. Media pieces like this from Newsweek describe the stability that existed in places like the Mathare slum and of how surprised some Kenyans themselves are of this outbreak of ethnic tension.
This other Newsweek story presents a grim account of gang violence in Nairobi, again based on ethnic identities. This was preceded by violence last year concerning a sect, the Mungiki, which committed atrocities and engaged in firefights with Kenyan police.

"Throughout much of last spring, in part because of the run-up to the elections but also for a host of other reasons, huge swaths of Kenya were succumbing to a particularly undulant, brutal kind of gangsterism. In episode after episode, many of which were documented by Kenyan reporters, innocent people were beheaded, skinned, raped, murdered and tortured by members of a secretive outlawed sect called Mungiki."
