DEIR AL-BALAH, Gaza Strip (AP) Israeli strikes on multiple homes in the northern Gaza Strip overnight and into Sunday left at least 87 people dead or missing, the territorys Health Ministry said.

Gazas Health Ministry says 87 people are dead or missing after Israeli strikes on multiple homes in northern Gaza.

It said another 40 people were wounded in the strikes on the town of Beit Lahiya, which was among the first targets of Israels ground invasion nearly a year ago. The Israeli military said it carried out a precise strike on a Hamas target.

Israel has been carrying out a large-scale operation in northern Gaza for the last two weeks, saying Hamas has regrouped there. Palestinian officials say hundreds of people have been killed and that the health sector in the north is on the verge of collapse.

The United States is meanwhile investigating an unauthorized release of classified documents that assess Israels plans to attack Iran , according to three U.S. officials. A fourth U.S. official said the documents appear to be legitimate.

The documents, attributed to the U.S. Geospatial Intelligence Agency and National Security Agency and marked top secret, indicate that Israel was moving military assets in place to conduct a military strike in response to Irans ballistic missile attack on Oct. 1.

The U.S. officials spoke on the condition of anonymity because they were not authorized to discuss the matter publicly.

The U.S. is urging Israel to press for a cease-fire in Gaza following the killing of Hamas leader Yahya Sinwar last week. But neither Israel nor Hamas has shown any renewed interest in such a deal, after months of negotiations sputtered to a halt in August.
