If you read through the linked twitter thread it seems like it’s a significant majority too. Obviously this is totally contrary to what Israel has previously claimed.
I also suspect that many of the civilian deaths were caused by the IDF using them as cover, especially at the festival.
In any case, next time someone talks about indiscriminately killing civilians, you can point out that unlike the IDF, Hamas has predominantly and objectively focused on military targets
If you take the case of Shani Louk, for example, it sounds like she was never taken hostage in the first place, but killed at the festival and her body put on the back of a truck and taken back to Gaza. Which is where that awful video of people spitting on her body comes from.
Israel found fragments of her skull at the festival site, so she was already dead when she was put back on that truck and taken to Gaza. But the people that had her body contacted her mother and tried to arrange ransom.
That is probably why the video, which has been so useful for Israeli propaganda, was released in the first place, to give the impression she was alive. After Hamas broke through the border lots of non-resistance Palestinians also came through and I would imagine some of them were probably chancers who committed violence or did things like this (trying to claim ransom for an already dead body).
None of that is to suggest Hamas didn’t also kill civilians, but if a ‘terrorist’ attack is able to get majority military targets what does that mean for the IDF when they are inflicting 99%+ civilian casualties?
