World leaders will gather at the UN General Assembly under the shadow of global divisions and ongoing conflicts in Gaza, Ukraine, and Sudan. UN Secretary-General Antonio Guterres highlighted the need for tough decisions to address the world's challenges, including conflicts, inequalities, and climate change. US President Joe Biden is expected to make a major appearance on the world stage, focusing on ending war and bringing hope to conflict-affected areas. Other speakers include Brazil's President Luiz Inacio Lula da Silva, Turkey's President Recep Tayyip Erdogan, Jordan's King Abdullah II, and Iran's President Masoud Pezeshkian, who accused Israel of seeking a wider war in the Middle East. The assembly's annual meeting follows the Summit Of The Future, which adopted a blueprint to tackle global challenges.
