After more than a year of devastating war, a ceasefire between Israel and Hamas is set to begin on Sunday, pausing the 15-month conflict between the two sides. The implementation of the deal is complex and fragile, requiring cooperation between various parties. The ceasefire has lifted spirits in Gaza, where the majority of the population has been displaced. In Israel, families are desperate to embrace relatives held captive by Hamas. The ceasefire goes into effect at 8:30 a.m. local time, with the release of hostages and prisoners planned for later in the day.
