Commentary:

You’re linking to the Times of Israel. Since the news outlet operates in Israel, it is subject to censorship by the IDF, and they have chosen to use their power to censor the article.

If you want information about assassinations of Iranian nuclear scientists, get their list from Wikipedia and google each of their names, looking for descriptions.

My guess: guided missile or drone strikes. All the assassinations happened at a time of Israeli air strikes over Iran. Whatever weapon was used, was deployed from airplanes. Given the high profile of the targets, Israeli intelligence agencies did their job this time (in Gaza, they seem to be feeding their troops AI slop).
