Yes, and it is very positive that prominent human rights groups agree and document it. These reports can be used to pressure governments, universities, etc. to divest from Israel and to stop sending arms, software, etc. to Israel.
Israel needs to step up their humanitarian aid and stop bombing them. Water was already an issue before, since Hamas used the pipes, that were installed with aid from the EU, to build rockets. They were proud of that and even used it in propaganda, as if that was somehow good? Propaganda video from Hamas. Why are so many people everywhere so fucked up :(
So you say that we don't know for sure that those were water pipes from the EU? Who cares if that detail is verified? Instead of actually working on improving the infrastructure, they destroy existing infrastructure to build weapons. That is the issue. Not whether or not that really was funded by the EU, that is/would be the cherry in top. Seeing how much money indeed was pushed into Gaza for aid, for example 600 million $ in 2020, it raises a lot of questions how much of that ended up financing weapons for Hamas instead of helping the people in Gaza.
