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

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.

Large explosions were reported across the Gaza Strip on Tuesday as the warring parties marked the two-year anniversary of Hamas' Oct. 7, 2023, attack and the start of the ongoing war in the Palestinian territory.

The Hamas-run Health Ministry said in a statement on Tuesday morning that at least 67,100 people have been killed by Israeli action in Gaza since the outbreak of the conflict.

Asked if he expects a Gaza or hostage deal on Tuesday, which will mark two years since Hamas' Oct. 7 attack on Israel, President Donald Trump said, "I think we’re going to have it soon."

"It's a hard thing for me to say that when for years and years, they’ve been trying to have a deal with Gaza," Trump said while taking questions in the Oval Office on Monday. "But we're going to have a Gaza deal, I'm pretty sure, yeah."

He cited the support of countries including Turkey and Saudi Arabia in trying to reach a peace deal.

"Everybody is on our side to get this deal done," he said.
