Key witnesses to Kenya's post-election violence in January 2008 are accusing the government of not doing enough to help them.

Campaigners have said at least 20 people have suffered intimidation because of the position they have taken against the attackers.

Al Jazeera's Andrew Simmons has this exclusive report on one man who informed authorities about a gang of men he says were armed and organised by politicians to kill people.

What he saw could implicate a government minister, other politicians and ex-military men in a campaign of murder.

More than 1,200 people died in the fighting that followed the country's disputed election.

No justice

There has been no official justice in the wake of the atrocities, which included the killing of women and children who were burned alive in a church, and what some of the witnesses say were civilians killed by police.

The International Criminal Court at the Hague has gathered evidence about the violence, but their inquiry still does not have the go-ahead.

Kenya is due to pass a law for witness protection but there has been no date set.
 
One witness who spoke to Al Jazeera has already given evidence to a commission investigating the post-election violence.

But since then he has had six threats warning him not to testify to the Hague.

Two years after the atrocities, which left more than a thousand dead, the alleged ring-leaders have still not faced trial.
