Two years since the war in Gaza began, thousands of Palestinians there are looking for relatives who have gone missing in one of the most destructive conflicts of the past decades.

Palestinians have been reflecting on the toll on their lives since Hamas's attack on Israel on 7 October 2023, which triggered the war.

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.

Before and after video shows much of Gaza reduced to ruins after two years of war. The war in Gaza began after a Hamas-led attack in southern Israel on October 7, 2023, killed over 1,000 people and led to the abduction of another 251.

Two years of war have left Gaza in ruins. Thousands have been killed. Many more are displaced and malnourished. Zediah has found shelter in a small, crowded room he shares with eight family members. He is able to cook lunch each day over an open fire. Once a week, he fills up water bottles from a nearby communal water distribution point.

Palestinian health authorities say Israel's two-year-old ground and air campaign against Hamas militants in the Gaza Strip has killed more than 67,000 people, with nearly a third of the dead under the age of 18.

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