The war began when Hamas-led militants attacked southern Israel, killing 1,200 people and taking about 250 hostages. Israel’s offensive has killed more than 52,000 people in Gaza, many of them women and children, according to Palestinian health officials. The officials do not distinguish between combatants and civilians in their count.

Israeli strikes on a school housing displaced families in northern Gaza killed 13 Palestinians on Wednesday, local health authorities said, as Israeli forces continued to demolish homes and buildings in Rafah in the south of the enclave.
