The International Committee of the Red Cross said its two staffers were killed and three wounded in Sudan's South Darfur, Paralel.Az reports citing TASS.

"It is with great sadness that the International Committee of the Red Cross confirms that two of its drivers were killed by gunmen on Thursday in South Darfur, Sudan. Three other ICRC staff were injured," the group said in a statement.

The incident occurred when a ICRC team was on its way from the settlement Layba where it assessed the humanitarian situation of communities affected by armed violence in the region.

"We are in deep mourning for our dear colleagues. We extend our sincere condolences to their families, and we hope for a speedy recovery for our injured co-workers," said Pierre Dorbes, the head of the ICRC delegation in Sudan.

The ICRC said its priority is to support those most affected by this tragedy, in particular the victims' families, relatives and colleagues.

The organization called for the immediate protection of all civilians, including humanitarian workers and medical personnel.

"They must never be directly attacked," the statement said.
