Early on Oct. 7, 2023, Hamas-led fighters launched a multipronged terrorist attack on Israel. The resulting war in Gaza has created a humanitarian catastrophe.

How many people have been killed in Gaza? How many Israelis died? What day did Hamas attack? Two years of war have devastated Palestinian society.

An ABC News analysis of dozens of satellite images from the last two years shows the massive destruction across nearly every area of Gaza.

White House spokesperson Karoline Leavitt said Steve Witkoff and Jared Kushner were on hand to take part in indirect talks between Israel and Hamas, which aim to end the war in Gaza.

At least 450 activists were aboard the flotilla, a coalition of several vessels seeking to deliver humanitarian aid to the blockaded Palestinian territory. Israeli forces detained them last week, and by Monday had deported Thunberg and 170 others to countries including Greece and Slovakia.

Israeli bombing has damaged or destroyed an estimated 80% of Gaza’s structures since the war started two years ago.

Israel has repeatedly denied permission to transfer incubators from an evacuated hospital in North Gaza, a U.N. children's agency official said on Tuesday, adding to strain on overcrowded hospitals further south where newborn babies are now sharing oxygen masks.

An Illinois veteran on a Gaza flotilla who was detained after the fleet of boats was intercepted has been released from custody.
