An Israeli bombing of a school turned shelter in Gaza City has killed at least 27 people, rescuers said, and hundreds of thousands in the Rafah area are fleeing in one of the biggest mass displacements of the war amid Israel’s newly announced campaign to “divide up” the Gaza Strip.

Three missiles hit Dar al-Arqam school in the al-Tuffah neighbourhood on Thursday afternoon, the civil defence agency spokesperson Mahmoud Bassal said, killing several children and wounding 100 people.

Another 20 people were killed in a dawn airstrike on the Shejaia suburb of Gaza City, bringing the total number of casualties reported by the local health ministry to 97 in the past 24 hours.
