Kinshasa - The UN has postponed the release of a draft report that accuses the Rwandan army of possible genocide in DR Congo.

It follows angry protests from Rwanda about details in the leaked draft, with Rwanda threatening to pull its troops out of UN peacekeeping missions.

The UN high commissioner for human rights says when the report is finally published on 1 October, it will have comments from concerned countries.

Rwanda has described the claims in the report as "insane".

The document, which was due to be published this week, accuses Rwanda's Tutsi-led army of killing Hutus in the Democratic Republic of Congo in the 1990s - acts it says may amount to genocide.

The UN draft report, which was leaked last week, says in the years following the genocide, the Tutsi-dominated Rwandan army went into neighbouring Zaire (now DR Congo) and killed tens of thousands of ethnic Hutus - including women, children and the elderly.

Extremist Hutus killed an estimated 800,000 Tutsis in Rwanda during 1994.

Rwanda contributes thousands of peacekeepers to the joint UN-African Union mission in the Sudanese region of Darfur, and the commander of the force is a Rwandan.

The UN report covers the wider conflict in DR Congo, which dragged in several neighbouring countries in what has been called "Africa's world war".

The document lists alleged rights violations by security forces from all the countries involved.

It accuses Congolese troops of involvement in the slaughter of ethnic Hutus - both Rwandan refugees and Congolese Hutus.
