- Fighting shows no signs of ending as the war between Israel and Hamas passes milestone date
- Here are five takeaways from the first 100 days of a conflict that has upended the Middle East

Sunday marked 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.

Israel responded with weeks of intense air strikes in Gaza before expanding the operation into a ground offensive. It says its goal is to crush Hamas and win the release of the more than 100 hostages still held by the group.
The offensive has wrought unprecedented destruction upon Gaza. But more than three months later, Hamas remains largely intact and hostages remain in captivity. The Israeli military says the war will stretch on throughout 2024.
