A ceasefire in the Israel-Hamas war is set to begin on Sunday at 0630 GMT, with the release of three Israeli hostages in exchange for Palestinian prisoners. The truce follows a deal struck by mediators Qatar, the United States, and Egypt after months of negotiations. The ceasefire is intended to pave the way for an end to over 15 months of war sparked by an attack on Israel by Hamas. The deal comes into effect on the eve of Donald Trump's inauguration as US president.
