3,500 South Sudanese stranded in Kosti since 2011 on Monday left Sudan for Greater Bahr El Ghazal.
South Sudan Relief and Rehabilitation Commission Chairperson Peter Lam Both told CRN on Monday that from Unity State the returnees are transported by land to Wau and Aweil.
He said South Sudanese and Sudanese teams together with NGOs took two months to organize the repatriation of the stranded returnees.
Mr Lam disclosed that some people decided to remain in Kosti because they were working in some farms.
He said that was their choice, but the government was encouraging everyone to return to South Sudan.
Mr Lam said the Commission is preparing to repatriate this month 41 thousand South Sudanese living in open spaces in Khartoum.
He said President Salva Kiir Mayardit directed the Finance Minister to release money for repatriating South Sudanese from Sudan.
