The prosecutor at the International Criminal Court (ICC) is set to announce the names of several Kenyans he accuses of being behind the violence that followed the disputed 2007 elections.
More than 1,200 people were killed and over half a million displaced.
In the peace deal that followed it was agreed that the perpetrators of the violence would face justice either in Kenya or at the ICC in the Hague.
Without court cases taking off locally, the ICC stepped in.
ICC prosecutor Luis Moreno Ocampo is focusing on two cases of post-election violence. He will name six suspects.
Each will be served with a court summons, but if they fail to turn up or they hinder the investigation, Mr Ocampo will request arrest warrants.
Senior politicians are expected to be on the list.
In recent days there has been a degree of panic amongst some members of the usually untouchable political elite.
Most Kenyans feel these prosecutions are vital in order to undermine the deeply rooted culture of impunity.
Search for justiceKenya has had a series of violent elections, but the disputed poll in 2007 saw the country taken to the brink of civil war.
Split along tribal lines, communities turned on each other with crude weapons as they were encouraged and even paid by power-hungry politicians.
The police used excessive force and carried out extra-judicial killings. More than 1,200 people were killed and half a million displaced.
The weapons were only put down after the former United Nations chief, Kofi Annan, brokered a peace deal between incumbent President Mwai Kibaki and his arch-rival, Raila Odinga.
As part of the peace deal, they agreed to ensure that perpetrators of the violence were prosecuted either in Kenya or in the Hague. The politicians thwarted all efforts to hold trials in Kenya and so the ICC stepped in.
In recent months several witnesses have been threatened, and the ICC has moved some out of the country.
The key question now is whether those accused will hand themselves over or be shielded by politicians and evade justice.
