Dozens of people were killed in Gaza, officials said Saturday, as protestors in Israel demand an end to the war in the Palestinian enclave and release of the remaining Hamas-held hostages.

Israel has called the United Nations' declaration of famine in parts of Gaza an "outright lie," but multiple U.N. bodies, more than 100 humanitarian groups, and several of Israel's own allies have warned for months that the war and Israel's restrictions of food into Gaza are causing starvation among civilians.
