The nutrition supply was looted during heavy fighting between armed factions in Upper Nile and Jonglei State, OCHA said.
UNOCHA said the ongoing insecurity is hampering the response, adding that humanitarian partners are unable to reach people left behind.
“In New Fangak, health and nutrition facilities were looted, and two schools were reportedly burned down,” OCHA said in a statement seen by Sudans Post on Friday.
It said staff from 14 organizations relocated from New Fangak to Old Fangak following the recent conflict in the area.
“Two nutrition facilities in New Fangak are non-functional as the nutrition and health workers are now part of the people impacted and displaced.”
“For people impacted, this protection crisis is exacerbated by trauma, continuous fear of conflict and worries over missing family members, due to family separations.”
It said separated children and survivors of gender-based violence are in urgent need of mental health and psychosocial support in a bid to close current gap in response.
“People’s needs include food assistance, shelter and core relief items such as plastic sheets, protection, health and water and sanitations services.”
“Humanitarian partners must deprioritize other response activities, including the flood response preparedness to respond to people impacted by the new emergency.”
