Over the weekend, the New York Times and Washington Post both reported on a “dossier of evidence” that detailed the alleged use of chemical weapons by the Sudanese Armed Forces (SAF).

The dossier, “shared by a Middle Eastern intelligence agency”, included images, documents and intercepted messages between Sudanese military officers that described how the army “developed and produced chemical weapons over six months in 2024”.

Multiple Sudanese and US sources have told Middle East Eye that the “Middle Eastern intelligence agency” is Israeli, and that the dossier it shared with the media was very similar to one Israel handed to the US government before it sanctioned Abdel Fattah al-Burhan, leader of the SAF, in January 2025.

The source of the evidence for the use of chlorine in Sudan raises questions about Israel’s involvement in the war and appears to confirm what multiple sources have told MEE, which is that the Israelis now side with the RSF – whose main patron is the UAE – over the SAF.

Israeli sources involved in their country’s decision-making in the Horn of Africa have previously told MEE that Israel sought to develop and maintain relationships with a variety of different players, rather than backing one side or another.
