BEIRUT (news agencies) — He is among the very last survivors of his Gaza family, a clan so close they knew without thinking how blood and marriage bound them across generations and city blocks.
Then, branch by branch, 173 of Youssef Salem’s relatives were killed in Israeli airstrikes in a matter of days in December. By spring that toll had risen to 270.
Bones and flesh strewn over the ruins of family homes. Blond curls of a young cousin peeking through bricks. Unrecognizable bodies piled on a donkey cart. Lines of burial shrouds.
These images are what survivors are left with from hundreds of families in Gaza like the al-Aghas, Salems and Abu Najas.
To a degree never seen before, Israel is killing entire Palestinian families, a loss even more devastating than the physical destruction and the massive displacement. An media investigation identified at least 60 Palestinian families where at least 25 people were killed — sometimes four generations from the same bloodline — in bombings between October and December, the deadliest and most destructive period of the war.
Nearly a quarter of those families lost more than 50 family members in those weeks. Several families have almost no one left to document the toll, especially as documenting and sharing information became harder.
Youssef Salem’s hard drive is stocked with photos of the dead. He spent months filling a spreadsheet with their vital details as news of their deaths was confirmed, to preserve a last link to the web of relationships he thought would thrive for generations more.
“My uncles were wiped out, totally. The heads of households, their wives, children, and grandchildren,” Salem said from his home in Istanbul.
In the last two decades, 10 members of his family were killed in Israeli strikes. “Nothing like this war,” he said.
The news agencies review encompassed casualty records released by Gaza’s health ministry until March, online death notices, family and neighborhood social media pages and spreadsheets, witness and survivor accounts, as well as a casualty data from Airwars, a London-based conflict monitor.
The Mughrabi family: more than 70 were killed in a single Israeli airstrike in December. The Abu Najas: over 50 were killed in October strikes, including at least two pregnant women. The large Doghmush clan lost at least 44 members in a strike on a mosque; news agencies documented over 100 family members killed in following weeks. By the spring, over 80 members of the Abu al-Qumssan family were killed.
“The numbers are shocking,” said Hussam Abu al-Qumssan, who lives in Libya and has taken over documenting the family death toll as his relatives in Gaza struggled to keep track.
In the 51-day war of 2014, the number of families that lost three or more members was less than 150. In this one, nearly 1,900 families have suffered multiple deaths by January, including more than 300 that lost over 10 members in the first month of the war alone, according to Gaza’s health ministry.
Ramy Abdu, chairman for the Geneva-based EuroMed Human Rights Monitor, which monitors the Gaza war, said dozens of his researchers in Gaza stopped documenting family deaths in March after identifying over 2,500 with at least three deaths. “We can hardly keep up with the total death toll,” Abdu said.
The killing of families across generations is a key part of t he genocide case against Israel, now before the International Court of Justice. Separately, the International Criminal Court prosecutor is seeking arrest warrants for two Israeli leaders for war crimes and crimes against humanity, including for the intentional killing of civilians, as well as for three Hamas leaders over crimes connected to the Oct. 7 attack.
Palestinians will remember entire families that have disappeared from their lives, Abdu said: “It is like a whole village or hamlet has been wiped out.”
The deaths across generations slice through the Palestinian society, history, and future. Entire families are buried in mass graves, in hospital courtyards or beneath staircases in the homes where they were killed.
Getting detailed images and documentation is difficult even for Palestinians. Power is limited to hospitals and Israel cuts communication networks frequently. Nearly all of Gaza’s 2.3 million population has been displaced, dividing families and severing contacts between parts of the small territory. Homes that normally would shelter a nuclear family fill with multiple generations of displaced relatives.
Hamas militants from Gaza attacked Israel on Oct. 7, killing 1,200 people in the deadliest day of the Jewish state’s 75-year history. Israel promised to destroy Hamas’ leadership and its estimated 35,000 fighting force in response. Within five days, Israel Air Force dropped 6,000 bombs on Gaza, including many unguided missiles.
Israel’s relentless bombing since has killed more than 37,000 Palestinians by early June, including many women and children.
