The United States has urged Sudanese leaders to ensure civilian rule and end violence against protesters after Abdalla Hamdok resigned as prime minister. "After PM Hamdoks resignation, Sudanese leaders should set aside differences, find consensus and ensure continued civilian rule," the US State Departments Bureau of African Affairs said in a tweet. Hamdok, an economist and former United Nations official widely respected by the international community, had served as prime minister under a military-civilian power sharing deal that followed the overthrow of former leader Omar al-Bashir in 2019. The military dissolved his government in a coup in October, but he returned a month later under a deal that tasked him with forming a government of technocrats ahead of elections in 2023. Hamdok announced on Sunday that he was resigning after being unable to forge a consensus to bring the transition forward. He called for dialogue to reach a new agreement for the transition. His resignation came hours after the latest round of mass rallies against the military. At least 57 civilians have been killed as security forces have moved to contain or disperse demonstrations since the Oct. 25 coup, according to medics aligned with the protest movement. Further protests are planned for Tuesday.
