Renewed heavy fighting in eastern Democratic Republic of Congo's (DRC) North Kivu Province has pushed some 3,000 Congolese refugees into northern Rwanda where they are in need of humanitarian assistance, says a senior UN official. 'The situation is worsening since humanitarian volunteers are now overwhelmed by the influx of Congolese refugees who are arriving in Rwanda,' Neimah Warsame, the UN Refugee Agency (UNHCR) representative in Rwanda, told reporters on 3 May.
