The United States has denied a visa to Abdel Fattah al-Burhan, Sudan's army chief and de facto leader, preventing him from attending the United Nations General Assembly in New York. The move effectively bars al-Burhan from addressing the world body at its annual high-level meeting. The refusal is a significant diplomatic signal, as the UN General Assembly gathering is a key forum for world leaders to engage with the international community, and Sudan remains embroiled in a devastating civil war between al-Burhan's army and the paramilitary Rapid Support Forces.
