Washington — Support for Israel’s military action in Gaza has declined substantially among U.S. adults, with only about one-third approving, according to a new Gallup poll — a drop from the beginning of the war with Hamas, when about half of Americans approved of Israel’s operation.

For months, the U.N. and experts have warned that Palestinians in Gaza are at risk of famine, with reports of increasing numbers of people dying from causes related to malnutrition.
