At least 200 returnees from Khartoum have been airlifted to South Sudan according to the Sudanese ministry of humanitarian affairs and the International Organization for Migration (IOM).
Priority has been given to the elderly and those with special needs in the latest voluntary return programme.
The director of Sudanese national center for the displaced Siir Umda confirmed that the 100 returnees have been taken to Wau and Aweil.
Umda said the airlifting exercise would continue on Saturday. 360 persons are expected to be repatriated in this airlifting exercise.
South Sudan's Minister of Humanitarian Affairs and Disaster Management Lual Achuil says his ministry and the ministry of gender and social welfare are working hand-in-hand to urgently bring back all the vulnerable groups from Sudan to South Sudan.
Achuil on Friday disclosed that over 200 people have been airlifted to Aweil in Northern Bahr-el-Ghazal and Wau in Western Barh-el-Ghazal States since the exercise started.
The minister urged the southerners in Sudan to return to South Sudan before the 4th April 2012 deadline given by Khartoum.
