This is something I was thinking about when I wrote the thing on the recent Mossad success or failure- depending on what you think should have been the end- murder or murder and secrecy.
In most publications, the murder of Naim Khader and other moderates has been attributed to Abu Nidal as kind of a collaborator killing type of thing. I think Khader was working unofficially on a peace deal with Israel with the help of Europeans or the UN or something.
In Victor Ostrovsky's book, By Way of Deception, among other observers, there is another school of thought- that Mossad was responsible. The first link below explains it rather well why this is more plausible than the typical Palestinian extremists killed the moderates line.
