According to officers of the Israeli military's Southern Command, the shelling was aimed at maintaining order at food distribution sites, but the army has since shifted to "other methods."
They only meant to drop shells near the aid stations, to keep the bad guys away. Gazans should make quantum leaps from where they are to inside the aid stations, without passing through the space near the aid stations. Duh.
Also notice how the long distance, chaotic distribution, and heavy aid boxes force families to self-select their strongest person, who would also be most able to put up a fight to defend their family. Then the IDF is gunning them down when they're in the chute, leaving starving women and children that are easily disposed of.
