## Summary

The US State Department imposed a new round of sanctions on Sudan's military-led government on July 20, accusing it of using chemical weapons, specifically chlorine gas, against RSF (Rapid Support Forces) paramilitaries during the ongoing civil war. The measures include airspace bans and financing restrictions. Sudan rejected the allegations as "false" and "politically motivated." The sanctions add to existing US restrictions on Sudan's warring parties.

## Why it matters

Chemical weapons use, if confirmed, crosses a widely recognised international threshold that typically triggers broader multilateral responses. The US sanctions signal that Washington intends to apply pressure on Sudan's government side, not just the RSF, in a conflict that has caused one of the world's largest displacement crises. Airspace bans affect Sudan's ability to import military equipment.

## What to watch

Whether other Western governments follow with coordinated sanctions; whether the Organisation for the Prohibition of Chemical Weapons (OPCW) opens a formal investigation; and Sudan's government response beyond the initial rejection.
