US 'concerned' by reports of Rwandan support for DRC rebels

Secretary of State Antony Blinken on Tuesday said the United States was "concerned" by "credible" reports that Rwanda is supporting rebels in eastern Democratic Republic of Congo.

The resurgence of the M23 group in Congo's restive east has exacerbated tensions between the neighbours, with Kinshasa accusing Kigali of backing the rebels.

Blinken was speaking in the Congolese capital Kinshasa, where he arrived on Tuesday for the second leg of a three-nation African tour and met President Felix Tshisekedi.

Rwanda has denied the allegations.

"We are very concerned by credible reports that Rwanda has supported the M23," the top US diplomat told a press conference in Kinshasa.

"All countries have to respect their neighbours' territorial integrity. Any entry of foreign forces into the DRC must be done transparently and with the consent of the DRC."

He said his trip to the region was to ensure US support for mediation efforts led by Angola and Kenya "to prevent further violence, to end conflict (and) to preserve the territorial integrity of the DRC".

The DRC is seeking international support as it struggles with Rwanda over the M23, a primarily Congolese Tutsi group that is one of many operating in the troubled east.

After lying mostly dormant for years, the rebels resumed fighting late last year, seizing the strategic town of Bunagana on the Ugandan border in June and prompting thousands of people to flee their homes.
