The finding should come as little surprise to the liberal Israeli publication. On November 9, Haaretz released an audio interview with Israeli reserve pilot Col. Nof Erez, who said the Netanyahu administration likely invoked the notorious Hannibal Directive, which dictates that Israelis taken captive should be killed by the military rather than left in the hands of Palestinian militants.

“Hannibal Directive was probably deployed because once you detect a hostage situation, this is Hannibal,” Erez told the outlet in a recording published November 9.

"What we saw here was a mass Hannibal,” the pilot concludes.

That sounds a little too unbelievable…

Apparently it was/is a real thing, but only applied to soldiers, not civilian hostages.

Still terrible, and IDF still killed the people they were trying to save, but I highly doubt they were intentionally killing them.
