I'm saying half because of the list they put out, but apparently it looks to be 700-800 civilians when counted. The list they originally put out on twitter was an image.
These are all still Israel's numbers, who are notorious liars. And we also know they were shooting and bombing hostages along with Hamas fighters indiscriminately during the battle.
You can see 'half' the image have Lt and Sgt on their names, sometimes in full. https://twitter.com/QudsNen/status/1722045168382021929
Jews were in high positions in the Arab world and iirc lived well. Much of the blame for the rise in anti-semitism is almost purely down to Zionism. Jews came to be seen as colonial collaboraters with the great powers against that region. In Algeria they literally were - the French were able to create a two-tier colonial society by giving Jewish Algerians who were native to Algeria citizenship and denying Muslims the same by claiming cultural incompatibility. Hence, Jews became a colonial force in that country.
In Iraq, Zionists terrorised the Arab (Iraqi!) Jewish community there by bombing Synagogues and cultural centers and collaborated with Iraqi nationalists to force Iraqi Jews into leaving for Israel.
So there are different experiences here, but almost all is down to colonialism and zionism.
