Kenya's bloody Sunday
Is it a return of an era of violence that Kenyans badly want to put behind them?
There is no shortage of theories about who was behind Sunday's blasts in Nairobi. But one theory stands above the rest.
The timing of the blasts is crucial here - less than 2 months ahead of a referendum in which Kenyans wil be voting on whether or not to adopt a new constitution. A huge amount is riding on this vote - the draft constitution is a key part of the the deal that ended Kenya's violence in 2008. The Kibaki - Raila unity government wants the constitution to pass.
But the target of the blasts - thousands of Evangelican Christians - do not. They were attacked while gathering in a public park to pray and listen to their leaders preach about the virtues of voting No in the upcoming constitution. They believe the blasts were planted by supporters of the Yes camp with the backing of the government.
And this is where the danger lies in as far as many Kenyans are concerned. The blasts are still being investigated. But should this belief have a grain of truth, it could signal the return of an era Kenyans badly want to put behind them - a time when political differences brought their country to the brink of a civil war.
