On Wednesday, the United Nations Office of the High Commissioner for Human Rights published a report alleging that Israeli forces carried out a mass execution of civilians in Northern Gaza, separating 11 men from their families and summarily shooting them.
That’s eleven men.

This is bad and I don’t want to justify or defend it. But this does not indicate mass executions of civilians as policy. It could well be a platoon leader who overstepped authority.
As the report states, the UN is calling for a formal investigation. As well they should.
