The War in Sudan

The Sudanese Army Uses Chemical Weapons on a Wide Front

The Sudanese army has built up a secret stockpile of chemical weapons, and tried to hide it. This is shown by a large amount of documents, videos, messages and other material that the Washington Post has reviewed.

The material indicates that the army has manufactured hundreds of chlorine gas bombs, hidden them on military bases, tested them far out in the desert and developed lists of targets where the poison gas can be used to penetrate enemy lines.

It would be a clear violation of the Chemical Weapons Convention, which Sudan signed in 1999.

Sudan's ruling military junta, including leader Abdel Fattah al-Burhan, denies any use of chemical weapons.

UN: Foreign support fuels war crimes in Sudan

A network of countries provides the Rapid Support Forces (RSF) – one of the warring parties in Sudan's civil war – with weapons, technology, fighters, training and logistics. This is according to a UN review according to Reuters.

The report identifies the United Arab Emirates, Colombia, Chad, Libya and Somalia as countries that support the RSF. The country's army, the other warring party, also receives foreign support, according to the report - but no specific countries are mentioned.

According to the UN, the foreign support contributes to the army and the RSF's ability to attack remote civilian areas with drones. Some of these attacks constitute war crimes, according to the report.

More than 1,000 people were killed in drone attacks in the first five months of 2026, according to the UN, which accuses both sides of serious human rights violations.
