Aid groups suspend operations

Several aid organisations have temporarily suspended operations in Sudan, as the violence rages on for a fourth day.

"This renewed fighting only aggravates what was already a fragile situation, forcing UN agencies and our humanitarian partners to temporarily shutter many of our more than 250 programmes across Sudan," said Martin Griffiths, the UN's emergency relief coordinator.

One third of Sudan's population, or 15 million people, face acute food insecurity and are in need of aid. 

Doctors Without Borders (MSF) said it received 183 wounded patients at the only hospital in Al-Fashir, the capital of North Darfur. It stated that 25 of those patients died. 

"The majority of the wounded are civilians who were caught in the crossfire - among them are many children," said MSF's Cyrus Paye.

On Saturday, three UN World Food Programme staff members were killed in Darfur, where humanitarian supplies have been looted, according to both MSF and Save the Children.
