Israel said it had launched a “precise strike” against Hamas militants operating from two school compounds in northern Gaza, as the family of a slain American lashes out at Israel.

Gaza’s Health Ministry says over 40,000 Palestinians have been killed in Gaza since the Israel-Hamas war began. It does not differentiate between fighters and civilians in its count. The war has caused vast destruction and displaced around 90% of Gaza’s population of 2.3 million, often multiple times.
