The United Nations Stabilization Mission in the Democratic Republic of Congo (MONUSCO) has so far rescued around 300 South Sudanese rebel troops on humanitarian grounds, who had crossed into the DR Congo, the agency said.
The rebels has fled South Sudan after the five-day heavy gun-fight in Juba between forces loyal to President Salva Kiir and those loyal to sacked first vice president Riek Machar.
Many of those rescued were wounded.
This rescue follows the August 17 extraction of Machar from a location within the DR Congo, along with his wife and son.
The UN meanwhile has said it is engaging both the DR Congo and South Sudan authorities as well as regional actors to help find a solution to the presence of armed troops in the DR Congo territory.
