Tens of thousands of Palestinians are returning to northern Gaza as a US-brokered ceasefire takes effect, raising hopes for an end to the Israel-Hamas war. However, questions remain about Gaza's governance and Hamas's disarmament. Israeli Prime Minister Netanyahu hinted at a potential renewal of military action if Hamas does not comply. The ceasefire marks a crucial step after a devastating two-year conflict that has resulted in significant casualties and displacement. Aid deliveries are set to increase, but the destruction in Gaza is extensive, with many returning to find their homes in ruins. The agreement includes the release of Palestinian prisoners in exchange for hostages, but concerns about the future persist.
