Smoke rises from the Gaza Strip during the ongoing bombardment by the Israeli military on Tuesday, Oct. 31, 2023. Over the past five days, Israeli ground troops have pushed deeper and deeper into Gaza in their war against Hamas, launched in response to a bloody Oct. 7 cross-border raid by the Islamic militant group. Yet even as the operation expands each day, the army refuses to call it an invasion. Its vague choice of words appears to be a deliberate strategy aimed at keeping its enemy off balance and preserving its options as a lengthy war unfolds. (AP Photo/Ariel Schalit)
