When a leaked intelligence dossier breaks open a decades-old taboo, the details are usually messy, brutal, and difficult to ignore. A massive trove of internal documents shared by a Middle Eastern intelligence agency has laid bare how Sudan’s military manufactured chlorine-based munitions during the height of its ongoing civil war.
If you have been following the devastating conflict between the Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF), you know that atrocities pile up daily. But the introduction of chemical weapons takes an already catastrophic humanitarian disaster into a darker, international-law-breaking territory.

Let's look at what the documents actually say, why the military turned to a common household and industrial chemical, and what this means for accountability moving forward.
Inside the Secret Dossier
The cache consists of nearly 150 documents, photographs, videos, voice notes, and thousands of text messages pulled straight from the cellphones of senior Sudanese military officers. This isn't vague hearsay or anonymous battlefield chatter. It is a detailed, bureaucratic trail of a covert military unit working over a six-month stretch in 2024 to weaponize chlorine gas. As discussed in detailed coverage by TIME, the effects are worth noting.
The papers include explicit bomb blueprints, field test reports, and text logs pointing directly to high-ranking officials. Among them, voice and text messages tie military chief General Abdel Fattah al-Burhan and Brigadier General Tariq Hussain to the core of the project. General Hussain ran the facility that assembled prototypes, combining conventional explosives with roughly 33 pounds of chlorine gas inside barrels meant to be dropped from Antonov cargo planes.
The logs read like a dark comedy of operational incompetence mixed with lethal danger. Chlorine gas leaked constantly from the crude prototypes. In one bizarre log entry, workers walked into a hangar in the morning to find dead insects and scorpions scattered across the floor, having suffocated overnight from drifting fumes.
Why Chlorine and Where Did It Come From?
You might wonder why a modern military would use chlorine instead of more sophisticated nerve agents like sarin or VX. The answer comes down to availability and control. Chlorine is not a heavily restricted substance globally because it serves a vital public health function: purifying drinking water.
That utility made it dangerously easy to acquire during a total war. According to the documents, the Sudanese military sourced its materials through a mix of international markets, including importing cylinders from Egypt, and diverting supplies straight from civilian infrastructure. Communications reveal that commanders requisitioned chlorine gas directly from the Al Manara water treatment plant in Omdurman—a critical facility meant to serve civilians trapped in the crossfire.
When mixed with moisture in human airways, chlorine turns into hydrochloric acid, causing instant, severe chemical burns to the respiratory tract. Deploying it as a choking agent from the sky violates the Chemical Weapons Convention, to which Sudan is a signatory.
The Cover-Up and International Fallout
Predictably, the Sudanese military has rejected the dossier's findings, calling them baseless and threatening legal action against publications reporting on the leak. Yet these internal records match the operational timeline that prompted the United States to slam General al-Burhan with direct sanctions.
Proving chemical warfare is notoriously difficult because it requires on-the-ground forensic investigations that are nearly impossible in an active war zone. Even so, independent open-source analysts and weapons experts reviewing the imagery note that the schematics and drop patterns align precisely with the chlorine barrel attacks documented around strategic locations like the al-Jaili oil refinery north of Khartoum.
The revelation changes the diplomatic calculus for Western nations trying to navigate Sudan's collapse. It strips away any pretense that the military's campaign is purely conventional, cementing accountability questions that will follow leadership long after the smoke clears.
Keep a close eye on upcoming international tribunal debates and UN General Assembly sessions where these documents will serve as primary exhibits. Real accountability starts with tracking how supply chains for dual-use chemicals are exploited by warring states, and closing the loopholes that let basic water treatment supplies turn into weapons of terror.
