The Israeli-Hamas war has already driven around 85% of Gaza’s 2.3 million people from their homes, leveling the northern part of the territory and heightening fears about a similar fate for the south as Israel’s air and ground offensive widens. The United Nations says tens of thousands of displaced Palestinians have streamed into the town of Rafah in the southernmost end of Gaza in recent days, crowding into an already overwhelmed area of the embattled territory. The Health Ministry in Gaza says more than 20,000 Palestinians have been killed since the start of the war. About 1,200 people were killed after Hamas raided southern Israel on Oct. 7, with around 240 people taken hostage.
