This article or rather it's usage is an example of antisemitism and a case in which more research would have been good. Questions like: how many, who, what for, what materials(tissue vs organs), how does it differ with other countries practices matter.

125 is the number mentioned in one Israeli lawsuit of tissues or organs (corneas are tissues) of people who had stuff taken out after/during obduction. This is not limited to Palestinian Arabs, but includes Jewish IDF soldiers, and others.

Israel had more restrictive law at that point than some European countries did. For educational and research purposes plenty of tissues could be taken (including in the GDR) and were taken before the pushes for transplantation laws in the 70s and 90s more and more changed the practice around the world. Requiring often previous consent (not needed in all countries), as well as separation of persons declaring dead, extracting organs and transplanting organs, and whether it is used for transplantation instead of research/education/military testing purposes.

All in all the rumor of all encompassing organ trafficking ring here isn't confirmed. Antisemitism is often the rumor about Jews and that something one did all do and never stop doing. That Jewish Israeli people did show the light on it and that the legal system didn't ignore it like with cases in the 80s in Germany is noteworthy.

There are from time to time reports of similar things, in a socialist society we ought to have opt out and a good transparent set of rules of what is allowed and separation of hierarchies.

The main problem I see here is whether the bodies of people were treated the same/different and that it is different if you do take tissues from bodies of people the de facto state doesn't recognize or are assigned hostile. However for those questions there is no solution within the EU, the USA and I am not sure about other states.

There are typically no laws that say: marginalized/homeless/stateless/tourists etc. are exempt from it. So the assigning people as hostile is the problem. A problem lately solved before October last year by forensic institutes in Gaza and West Jordan doing the work.
