The video is only shocking because there's blood. Otherwise it just looks like a Prisoner of War situation. They are constantly cutting it and only keeping in shocking images or removing all context from each interaction so it can only have the least charitable interpretation.
From what I could see, they took the prisoners of war (captured from a military base, which is a legitimate military target) to a FOB, interviewed them with questions about where in Israel they're from and the phone numbers of their family, then loaded everyone onto transport keeps and likely left the active front to go to a more permanent base/camp.
No one was killed, no one even got hit or hurt. One person was just yelled at because they kept talking and another just said she had a friend in Gaza and gave them her number.
