Who Killed Imad Mughniyeh?

The Times of London is claiming the Israelis were responsible, and judging by the blog posts on the subject and assorted commentary in reaction, it seems that many are jumping to conclusions and taking the story to be 100% true. However, Israel Matzav notes:

I have to give an Uzi Mahnaimi alert because he is one of the authors of the article. The only named source is described as "a former major in unit 504 of Israeli military intelligence who was in charge of Mughniyeh’s file." If my google search of the source is correct, he is currently living in the United States and is not likely to be privy to the current goings on in military intelligence. In short, while I believe that the manner of the killing may be correct, I have serious doubts whether Israel really did it. And as to what Mugniyah had been up to in the last two years, anyone could have guessed that.

SoccerDad is skeptical as well. So is Lawhawk.

Reliapundit speculates about the possibility of it having been an inside job:

• I WOULD NOT BE SURPRISED IF MUGHNIYEH'S ASSASSINATION WAS INTERNECINE: JUST AS IRAQIS HAVE KILLED MORE IRAQIS THAN USA HAS KILLED IRAQIS SINCE 2003, MUSLIMS HAVE KILLED MORE MUSLIMS THAN NON-MUSLIMS HAVE KILLED MUSLIMS.

• PEOPLE WHO MURDER THEIR OWN DAUGHTERS TO RESTORE FAMILY HONOR ARE CAPABLE OF VIRTUALLY ANY OTHER ATROCITY - INCLUDING INTERNECINE WAR, AND INCLUDING NUKING... WELL, ANY CITY IN THE WORLD THEY CAN.
