NAIROBI: Intense fighting in South Sudan has prevented desperately needed food from reaching some 60,000 malnourished children for almost a month, the UN said on Thursday.

South Sudan has been wracked for years by insecurity and political instability, but recent clashes in Upper Nile State between forces allied to President Salva Kiir and his rival, Vice President Riek Machar, have alarmed observers.

In a joint statement, the World Food Programme and the UN children’s agency, UNICEF, warned that escalating fighting along the White Nile river — a major transport route — has meant “no humanitarian supplies have reached the area in almost a month.”

The area in the north of the country already had “over 300,000 children affected by moderate or severe malnutrition in the past year” and was at “breaking point.”

“Every day makes a difference for a malnourished child in need of life saving treatment,” said WFP’s South Sudan representative, Mary-Ellen McGroarty.

The agencies said almost 2,000 cartons of lifesavingnutrition supplies had been stolen since the uptick in hostilities.

UNICEF representative Obia Achieng said there was an “unprecedented” break in supply lines due to the ongoing fighting, looting, and disruption of the river route.

“If this continues, we are in danger of simply running out of supplies in counties across the state by the end of May 2025, with potentially catastrophic results for the youngest, most vulnerable children,” Achieng said.

South Sudan has been unstable since gaining independence from Sudan in 2011.

Kiir and Machar fought a five-year civil war that cost some 400,000 lives, and was only ended by a power-sharing deal in 2018 that has almost entirely collapsed in recent months.
