Thousands of people have fled fighting in the Democratic Republic of Congo over the past month and sought refuge in neighbouring Angola.
A provincial governor Ernesto Muangala, said the exodus of Congolese due to fighting in their home country is straining resources in villages along the border.
Mr Muangala said officials counted more than 20 000 refugees in the Lunda Norte Province almost double the number recorded a month ago.
The people had fled clashes between Congolese government and militia forces that erupted in Congo’s Kasai-Central Province in July, then spread to four other provinces.
Mr Muangala said the refugees would be moved from overcrowded villages to a refugee camp in Lovua, about 1 000 kilometres east of Angola’s capital Luanda.
