People lift national flags during a rally called for by Sudan's Popular Front for Liberation and Justice in Port Sudan on April 24, 2025, to denounce the siege imposed by the paramilitary Rapid Support Forces (RSF) on El-Fasher city and express support for its residents. Since April 2023, the war between the army and the RSF has killed tens of thousands, uprooted 13 million and created what the UN describes as the world's worst humanitarian crisis. El-Fasher, the state capital of North Darfur, remains the last major city in the vast Darfur region that the paramilitary group has not conquered. (Photo by AFP)
