Insecurity and horrific sexual violence in eastern Democratic Republic of the Congo (DR Congo, DRC) have forced tens of thousands to flee across borders, with no sign of the exodus stopping, the UN Refugee Agency (UNHCR) said on Tuesday. UNHCR reiterated its call on all countries to allow access to their territories for civilians fleeing conflict and violence in DRC, to guarantee the right to seek asylum and to ensure respect for the principle of non-refoulement.
