During the 11-day war between Israel and Palestinian militants in May 2021, Israeli airstrikes destroyed five multi-storey towers in the heart of Gaza City. The images of buildings crumbling to the ground flashed across TV channels around the world as Gaza faced the most intense Israeli offensive since 2014. At least 256 Palestinians were killed, including 66 children, and 13 in Israel, including two children. Israel claimed it was destroying the military capabilities of Hamas, who had fired rockets at Israel after weeks of tension in Jerusalem over the planned displacement of Palestinian residents and police raids on al-Aqsa mosque during Ramadan.

Each time Israel said it was targeting Hamas and that it had warned the residents first. But what is it like to have only a few minutes to evacuate before watching your life collapse into rubble?

In conjunction with the civilian harm monitoring organisation Airwars, the Guardian spoke with dozens of residents and gathered footage and photos to piece together the story of one building, al-Jalaa tower, demolished by an Israeli airstrike on 15 May 2021. These are the stories from inside the tower, of the Mahdi clan, who owned and lived in the building, the Jarousha family and the Hussein family.
