Quick Summary

A dossier made public on Saturday presents evidence of Sudan's military developing and using chemical weapons during the country's civil war, according to documents, videos, and text messages provided by Middle Eastern security officials. The allegations are based on an April 2025 US determination that Sudan's government used chemical weapons in 2024, which was met with limited public evidence at the time. No specific numbers or statistics are mentioned in the article. The report comes as part of a broader concern over human rights abuses and atrocities committed by both sides in the war, which has created the world's worst humanitarian crisis.

Story summary

A new dossier has been released, allegedly showing Sudan's military producing and stockpiling chlorine-based weapons for use against the Rapid Support Forces, a rival group in the country's civil war. The documents, videos, and text messages were provided by Middle Eastern security officials from an unnamed country to The New York Times and The Washington Post. This comes after the US government determined in April 2025 that Sudan's government had used chemical weapons in 2024. If true, this would add to the growing list of human rights abuses and atrocities committed by both sides in the conflict, which is considered the world's worst humanitarian crisis. The allegations suggest that Sudan's military has been secretly developing and using these weapons despite little public evidence being presented.
