Rwanda says reports that UN Security Council experts have found "solid evidence" that the country is working with and supporting the M23 rebel group in the east of the Democratic Republic of Congo are false, unproven and a "tactic to distract from real issues".
Their comments come hours after DR Congo government spokesman Patrick Muyaya welcomed the work of the UN group, saying that the country hopes that conclusions would soon be reached to put an end to Rwanda's interference and bring back lasting peace.
The Reuters news agency revealed on Thursday that the confidential report by UN experts found evidence that M23 fighters and Rwandan troops jointly attacked a large Congolese army base in Rumangabo, in eastern North-Kivu province on 25 May.
Rwanda has repeatedly denied allegations it supports the M23 rebels.
Kigali in turn accuses Kinshasa of shelling its territory.
Tensions between the two countries escalated this year following a resurgence of activity by the rebel group.
Earlier this year, the Congolese government suspended all RwandAir flights from the country over Rwanda’s alleged support of the rebels.
