The world's largest humanitarian disaster continues to claim victims as the war in Sudan drags on. On Wednesday, 20 months into the conflict, the US called the actions of one half of the conflict genocidal and imposed sanctions on its leader. Mohamed Hamdan Dagalo, also known as Hemedti, leads the RSF paramilitary forces that have been battling the army for control of the country since April 2023. But the army has also been accused of atrocities in a war that's claimed an estimated 150,000 lives.
