Israel-Gaza live updates: Hamas publishes names of 20 living Israeli hostages to be released

Israel, in the second year of the war, continued hunting militants throughout the Gaza Strip, proceeding at times in block-by-block sweeps of neighborhoods and buildings.

Across the devastated territory, civilian casualties climbed, mass hunger spread and the Israel Defense Forces repeatedly forced large numbers of Palestinians to relocate.

Since returning to office in January, U.S. President Donald Trump has twinned a push for a peace deal with apocalyptic threats against Hamas.

This week, Hamas, Israeli and U.S. representatives are gathering in Egypt's Red Sea city of Sharm el-Sheikh for talks on Trump's proposed ceasefire deal, which he has framed as "something special" for the entire Middle East.

Since Hamas' Oct. 7, 2023, terrorist attack against Israel and Israel's military response in Gaza, an ABC News analysis of dozens of satellite images from the last two years shows the massive destruction across nearly every area of Gaza.

The images show entire towns and neighborhoods have been ravaged in Gaza, alongside key infrastructure like schools, hospitals and religious buildings.

As many as 197,000 buildings have been damaged or destroyed during the war, according to estimates in a damage analysis shared with ABC News of Copernicus Sentinel-1 satellite data by Corey Scher and Jamon Van Den Hoek of Oregon State University's Conflict Ecology lab.

Two years on from Hamas' Oct. 7, 2023, attack, Israelis are mourning the 1,200 people killed in the attack and remembering the 251 people taken hostage.

The anniversary falls on Sukkot, a weeklong Jewish holiday that follows Yom Kippur. Government offices are closed as are some businesses. The official government marking of the anniversary will take place on Oct. 16.

Throughout Tuesday morning, crowds of people returned to the site of the Nova Festival in southern Israel close to the Gaza frontier. They laid flowers, lit candles and held a minute's silence in memory of more than 360 people killed there by Hamas on Oct. 7.

This evening in Tel Aviv, the Hostage and Missing Families Forum will hold an event in Hostages Square. Thousands of people are expected to attend.
