Cairo - The United Nations said on Tuesday that the attack on aid convoys in Darfur, Sudan, killed five people.

On Monday night, the attack on a convoy of 15 trucks occurred in the town that quickly supported the troops-controlled by the troops in the northern Darfur province. It attempts to reach El-Fasher City, according to a joint statement from the World Food Program and UNICEF. Two agencies called for an investigation into the attack.

More than two years ago, Sudan was caught in a war when tensions between the Sudanese army and its rival paramilitary RSF quickly spread in the Khartoum capital in amidst street fighting across the country.

Many trucks were burned and damaged aid and injured members of the convoy, the statement said. It did not say who was responsible for the attack.

"It is devastating that these supplies have not yet reached the vulnerable children and families they intended to be vulnerable," the statement said.

WFP and UNICEF said they are negotiating a completion of a El-Fasher trip to RSF, which is a temporary seat on the country's military government on the Red Sea after more than 1,800 kilometers (1,100 miles) from the port of Sudan in eastern Sudan.

The RSF said in a statement that the convoy was hit by a military aircraft during a "pre-attack." Video shared by RSF shows that the burning vehicle carries something that appears to be a flour bag.

However, the military-led government rejected the charge and said in a statement that the AIDS trucks were “attacked by attacking drones from operations by rebel Rapid Support Forces (RSF) militias.”

El-Fasher's resistance committee tracked the battles in and around the city and accused paramilitary personnel of attacks, saying the RSF statement was intended to "mislead public opinion and evade accountability."

El-Fasher is more than 800 kilometers (500 miles) southwest of Khartoum and is one of the last strongholds of the Sudanese army in Darfur. The region has been under attack by RSF since May 2024.

Monday's attack was the latest aid operation in the past two years. Last week, WFP's location in El-Fasher was blown up, damaging a workshop, office building and clinic, the statement said.

The war has caused the world's worst humanitarian crisis. It has sent about 13 million people to their homes, including more than 4 million people passing through neighboring countries. Part of the Sudan was pushed into famine.

According to the United Nations and International Rights Organizations, the sign of fighting is atrocities, including mass rape and racially motivated killings, which amount to war crimes and crimes against humanity, especially in Darfur.
