Democratic Republic of Congo on Tuesday registered some 7,000 refugees arriving from war-torn South Sudan. Local officials reported.
"Seven thousand people have crossed the South Sudanese border at Dungu towards the Democratic Republic of Congo," said Ismael Arama Ziama, senior official in Haut-Uele province.
Arama Ziama said that the refugees who have arrived over the last month were "fleeing the climate of insecurity in the [South Sudanese] provinces bordering the DRC."
Although most of the refugees are from south Sudan, there are some minorities in the group, including Congolese and other nationals, he added.
The town of Dungu in Haut-Uele province lies some 80-kilometres (50 miles) from the South Sudanese frontier.
The civil war, which broke out in December 2013, plunged the young African nation into a vicious circle of retaliatory killings after President Salva Kiir accused his former Deputy, Riek Machar, of plotting a coup.
As clashes between rebels and government troops intensified in the unity state of South Sudan, aid agencies withdraw and tens of thousands were forced to leave their homes, last May.
"Since the beginning of May, military activities south of Bentiu in Unity State have forced up to 100,000 people from their homes," the UN's Humanitarian Coordinator, Toby Lanzer, for South Sudan said.
The country is now treading a hate-stricken path of racial tensions, ethnic massacres, rape and the use of child soldiers.
The UN estimated 10,000 people have been killed and another 1.5 million displaced, since the conflict began.
Also, cholera and starvation are another substantial issues in South Sudan.
At least 167 people died in South Sudan in a cholera outbreak last year, according to the World Health Organisation.
