IDF says “immense quantity” of friendly fire, that doesn’t sound like your “a few”:
Israel’s army on Tuesday admitted that an “immense and complex quantity” of what it calls “friendly fire” incidents took place on 7 October.
The key declaration was buried in the penultimate paragraph of an article by Yoav Zitun, the military correspondent of Israeli outlet Ynet.
It is the first known official army admission that a significant number of the hundreds of Israelis who died on 7 October were killed by Israel itself, and not by Hamas or other Palestinian resistance factions.
Citing new data released by the Israeli military, Zitun wrote that: “Casualties fell as a result of friendly fire on October 7, but the IDF [Israeli military] believes that … it would not be morally sound to investigate” them.
"While this is not a conclusive finding, it is currently considered the likeliest explanation based on the evidence gathered in investigations conducted by the Associated Press, CNN, The Economist, The Guardian, and The Wall Street Journal.[7]"
No official investigations made (only statements made by pro-israel media eraly in conflict), no proof thefore. Yet israel has track of bombing the Gaza hospitals, which makes aposteriori a more plausible explanation for the incident.
Regardless a failed rocket launch is a different matter from the Hannibal Directive which is deliberate lethal attack on their own hostages. The official directive was retired in recent years but is still practiced per Israeli reporting.
> The Hannibal Directive (Hebrew: נוהל חניבעל; also Hannibal Procedure or Hannibal Protocol) is 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."
> Israeli newspapers have reported that the IDF was issued orders echoing the wording of the Hannibal Directive during the 2023 Hamas-led attack on Israel. The IDF was ordered to prevent "at all costs" the abduction of Israeli civilians or soldiers, possibly leading to the death of a large number of Israeli hostages.
There's lots of proofs of misfires, hospital incident aside Hamas and Islamic Jihad rockets are in many cases low quality and disintegrate in the air or just miss completely and land in Gaza. I'm sure you can find articles about it if you wanted to look.
