May 2 (UPI) -- An armed opposition group released 10 South Sudanese aid workers kidnapped in April after holding them for five days, the United Nations announced.
The humanitarian coordinator for South Sudan, Alain Noudehou, said the 10 workers were returned safely and in good health Monday. Their abduction took place April 25 s the workers were en route from Yei to Tore as part of an aid convoy.
Of the 10 who were kidnapped, one was from the U.N. Office for the Coordination of Humanitarian Affairs, two from the U.N. International Children's Fund, one from the South Sudanese Development Organization, two from South Sudanese NGO Across, three from Plan International and one from Action Africa Help.
Noudehou said it was the second abduction of aid workers in April and third in six months.
"I am deeply concerned by the insecurity faced by aid workers in South Sudan, who are risking their lives to save others," he said. "I strongly urge the parties to the conflict to abide by international humanitarian law and ensure that humanitarians are safe while delivering assistance and services to people in need."
