Uganda's President Museveni Thursday said it would be “unfortunate” if reports that Rwanda is supporting the M23 militia in Congo turned out to be true.

Speaking to BBC in an interview Thursday evening, the President said “Rwanda or no Rwanda” there are unresolved issues in Congo, including the matter of several armed fighting groups in the east of the country.

His comments came after a senior Congolese diplomat said Thursday that Rwanda had invaded his country, as the UN deployed peacekeepers to Goma, the biggest city in the east of the country, to protect it from the M23 armed rebel group.

Speaking to BBC and Al Jazeera TV, the DR Congo’s envoy to the UK, Barnabe Kikaya bin Karubi, said: “We now have concrete evidence that Rwanda has invaded the DRC.”

Rwanda denies allegations that it is behind the insurrection by the M23 rebels who captured Bunagana Town on the border with Uganda, and Rutshuru town, before threatening to march on Goma.

This newspaper could not independently confirm reports filtering in Thursday that the rebels had been forced to pull out of some of the towns it had captured by advancing FARDC (DR Congo government troops), although they remained in charge of Bunagana

The human rights group Amnesty International called upon the UN Security Council to call on the Rwandan government to stop providing support for the M23 armed group in DR Congo’s North Kivu Province, the UN redeployed peacekeepers to Goma.

“While redeploying UN troops to Goma to protect civilians is a positive step, the situation in the North Kivu is so tense that it has the potential to turn into a regional conflict if the international community does not take urgent measures,” Aster van Kregten, Amnesty International’s deputy director for Africa, said.

“I hope you are not hearing those Amnesty reports for the first time and I hope you have the resolution of ICLR? They are telling Congo to solve its internal problems,” Mr Mugambagye said.
