On Oct 7th numerous instances of ‘Hannibal Directive’ have been made evident. The most extensive casualties are due to 28 attack helicopters (“Apache”) emptying their full complement of weapons (“shoot everything”) and re-arming through the course of the morning hours of that day. Other known incidents have been reported of tanks firing on homes known to have hostages inside under orders from command. There are also reports of drone operators firing at vehicles and other targets that likely had hostages contained within. This list of links focuses mostly on the evidence of the helicopter attacks.

What is the Hannibal Directive?

"the name of a controversial procedure that was used by Israeli Defense Forces (IDF) until 2016 to prevent the capture of Israeli soldiers by enemy forces. According to one version, it says that "the kidnapping must be stopped by all means, even at the price of striking and harming our own forces."[2] It was introduced in 1986, after a number of abductions of IDF soldiers in Lebanon and subsequent controversial prisoner exchanges. The full text of the directive was never published, and until 2003, Israeli military censorship forbade any discussion of the subject in the press."  

TL;DR: A policy of killing hostages instead of allowing them to be taken alive.
