"The United States calls on the government of Sudan to cease all chemical weapons use and uphold its obligations under the CWC," the statement read, referring to the Chemical Weapons Convention under which signatories have committed to destroy their stockpiles of the weapons.

The US says it will hit Sudan with sanctions from June 6 over use of chemical weapons amid ongoing civil conflict.

The US said it would impose sanctions on Sudan, to take effect around June 6, after determining that its government used chemical weapons in 2024 during the army's conflict with the paramilitary Rapid Support Forces.
