Israel’s government warned that Hamas “is continuing to hold to unrealistic demands” as it prepared to review the latest cease-fire proposal Friday. A ship carrying 200 tons of food — the first attempt to deliver aid by way of a maritime corridor — began offloading its cargo into Gaza on Friday. The boat left Cyprus earlier this week, dispatched by the U.S. nonprofit World Central Kitchen, founded by celebrity chef José Andrés, and the Spanish search-and-rescue group Open Arms.
