A UN report into the killings of Hutu civilians in the Democratic Republic of Congo during the 1990s says they may constitute "crimes of genocide".

It accuses Rwandan, Ugandan and Burundian forces of participating in the attacks, and recommends that the international community seeks to prosecute those responsible.

The document's publication prompted angry denials from all the countries.

But the Congolese government said the report was credible and heartbreaking.
