The cynic in me thinks the IDF would not use $3000 in munitions to kill four random guys. Bullets are dirt cheap fpv bomb drones are expensive. From that I can only assume someone really wanted to kill one of them for some reason that we can not determine from the limited footage. I’m not saying war crimes including intentional starvation and indiscriminate fire are not happening but I don’t think this is one of them this looks far too coordinated and planned to be a random act of aggression.
