Bhutto assassinated.. by who?

It seems that Benazir Bhutto has been assassinated. The first time I read this article... well it seems to me..

Pervez Musharraf hated this woman, but now that this happens he declares three days of mourning, and conveniently blames it on this unnamed 'extremist' organization that he supposidly declared martial law to fight. A martial law that Bhutto opposed. Two birds with one stone anyone? Taking her out and blaming it on his imaginary enemies would both eliminate his opposition and cause some of her supporters to take his side, imagining that he was trying to find her killer despite being the killer himself.

There's your conspiracy theory of the week. I have no information, so I don't know, but it sure seems like a great plan to me.
