Entire lineages, often four generations of the same family, have been killed in single or many attacks on members of the same family who were sheltering from the bombs.

An Associated Press investigation identified at least 60 Palestinian households in which 25 or more individuals were murdered in bombings between October and December in what was called the bloodiest and most damaging chapter of the war,  which is currently in its ninth month.

Key findings from the analysis indicate that several families have nearly no one left to register the toll, and thousands are unable to account for all of their relatives due to the huge numbers still under the debris.
