The US has accused the Sudanese paramilitary Rapid Support Forces (RSF) of committing genocide and imposed sanctions on its leader. US Secretary of State Antony Blinken on Tuesday said Mohamed Hamdan Dagalo, also known as Hemedti, was being punished for his role in "systematic" atrocities against the Sudanese people during the 20-month conflict.

The Biden administration says it has determined that Sudan's Rapid Support Force rebel group and proxies are committing genocide in the country's civil war.
