"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 will cut exports to Sudan and lines of government credit after determining that banned weapons were used.

The United States has announced new sanctions against Sudan after concluding that the Sudanese government used chemical weapons during its ongoing conflict with the paramilitary Rapid Support Forces (RSF).
