(FILES) This file photo taken on August 12, 2016 shows Rwandan President Paul Kagame (L) and Democratic Republic of the Congo's President Joseph Kabila (C) talking at the Rwanda-DRC border in Rubavu after concluding bilateral discussions. The United States warns of further violence in the already war-wracked Democratic Republic of Congo should President Joseph Kabila hold on to power after his mandate expires in December. Kinshasa, meanwhile, speaks of "chaos" if foreign countries meddle in the crisis. For months, Washington has kept a close eye on the DRC, where tensions are running high ahead of the December 20 deadline for the end of the president's second term. He is barred from running again under the constitution. / AFP PHOTO / CYRIL NDEGEYACYRIL NDEGEYA/AFP/Getty Images
