NAIROBI - The United States on Monday called on Rwanda to publicly denounce rebels who have seized swathes of eastern Congo in an appeal that highlighted its frustration over Kigali's alleged role in its neighbor's conflict.

Rwanda has repeatedly denied supporting the M23 rebel movement in the eastern Democratic Republic of Congo, blaming Kinshasa and major world powers for failing to tackle the problems that led to the uprising.

But it has not so far publicly condemned the M23 movement and donors, including the United States, one of Kigali's closest allies, have slashed aid to the tiny central African nation as the result of a United Nations report which concluded Rwandan officials were supplying the rebels with weapons and logistics.

"It is not and should not be too much to ask the government of Rwanda to denounce a rebel group that is preying on the lives of people or undermining the stability of a neighbor," Johnnie Carson, the US assistant secretary of state for African affairs, said in a teleconference on Monday.
