The report that I saw said that there were 70 vehicles completely destroyed by RPG or Helicopter and the Israeli military did not go into specifics(although they undoubtedly have more data about the event than they have released)
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.
