JOHANNESBURG – A U.N. draft report says the Rwandan army and Congolese rebel allies now in power committed massacres of Hutu refugees in Congo in the 1990s that could be classified as genocide.

Le Monde newspaper of Paris reports that the draft says Rwanda's president is threatening to withdraw troops from peacekeeping missions if the genocide allegation is published.

About 1 million Hutus including perpetrators of Rwanda's 1994 genocide fled to Congo. Rwandan troops invaded. Thousands were slaughtered in U.N. refugee camps.

The draft from the High Commissioner for Human Rights says systematic and widespread attacks "could be classified as crimes of genocide" by a competent court.
