TRIBAL rights group Survival International has condemned German and United States authorities for funding the massacre of indigenous people in the Democratic Republic of Congo.

Guards patrolling the Kahuzi-Biega national park have committed a series of horrific atrocities against the indigenous Batwa people, whose lands were taken to create the park, famed for its gorilla-spotting treks, the organisation said. 

At least 20 Batwa people have been killed and dozens of women have been gang-raped at gunpoint, while children have been burnt alive during joint patrols with the Congolese military, according a new report by Minority Rights Group International.
