This has stalled Gaza’s ability to rebuild after the 2014 Israeli offensive, which destroyed 18,000 homes. About 75,000 people remain displaced, according to the United Nations, with many still living in temporary corrugated iron structures. Several babies died this year amid freezing conditions and a lack of heating.
