Local health officials say at least 38 Palestinians were killed overnight and during the day in the Gaza Strip while seeking aid from United Nations convoys and sites run by an Israeli-backed American contractor. The Israeli military said on Wednesday it had fired warning shots when crowds approached its forces. Another 25 people were killed in Israeli airstrikes. That's according to local hospitals in Gaza. The latest deaths came as Prime Minister Benjamin Netanyahu was expected to announce further military action — and possibly plans for Israel to fully reoccupy Gaza. Experts say Israel's ongoing military offensive and blockade are already pushing the territory of some 2 million Palestinians into famine.
