In case you missed it
It is the case in every example of military attack that women and children are given priority "WOMEN AND CHILDREN FIRST" (ever hear of that one?
In the case of there not being sufficient places of relative safety older boys and men take their chances where they can and invariably bear the brunt of having to do so
Please point out which bit of this is difficulty to understand.
"No. I am just putting Israel's side of the story."
You never put, or even listen to any other side of the story.
