As I understand, less than 100 civilians were killed in strikes on refugee camps and on humanitarian corridors. War is hectic and so was the evacuation. This is again one of the examples of something tragic that happened once or twice, and people reporting on it as of it was the only thing happening.
If there were indiscriminate bombings on such locations, that would be evidence of war crimes. They seem very discriminate to me. IDF claims in one such attack, they got 40 Hamas members or something having a meeting in a mosque, of course they barred the doors and had a bunch of women and children in there with them to be used as human shields. Their deaths therefore are on Hamas, they locked them in there because they knew what could happen and they get sympathy when they do, instead of being held responsible for all the innocent lives.
