A very important bit, reported by WSJ:
The ATACMS models that were provided have a range of about 100 miles.
Pravda is also quoting WSJ in their article and mentioning the 160 km range version. https://www.pravda.com.ua/eng/news/2023/10/17/7424525/
Lots of Islamic Jihad & Hamas missiles fail during flight and kill Palestinians. Israel had published videos in the past showing e.g. 8 launches at night, pausing the video and showing how 2 or 3 suddenly turn down to the ground to hit the Gaza strip. And of course the local terrorist groups accounted dead Palestinians to Israel striking those locations. It's sometimes easy to show, with visible rocket engines at night and sometimes harder.
