Sunday marks 100 days that Israel and Hamas have been at war. The war already is the longest and deadliest between Israel and the Palestinians since Israel’s establishment in 1948, and the fighting shows no signs of ending.

Israel declared war in response to Hamas’ unprecedented cross-border attack on October 7 in which the Islamic militant group killed some 1,200 people, mostly civilians, and took 250 others hostage. It was the deadliest attack in Israel’s history and the deadliest for Jews since the Holocaust.
