Gaza’s Health Ministry says 87 people are dead or missing after Israeli strikes on homes in northern Gaza. It says another 40 were wounded in the strikes on the town of Beit Lahiya overnight and into Sunday. A large-scale operation continues against Hamas militants said to be regrouping in the north. Meanwhile, the United States is investigating an unauthorized release of classified documents that indicate that Israel is moving military assets in place to strike in response to Iran’s ballistic missile attack on Oct. 1. Iran supports both Hamas and the Lebanon-based Hezbollah.
