Provenance for Musharef, yes, but didn’t Bhutto, herself state that Al Queda was out to get her? This is not necessarily good for Musharef because he will be blamed and it’s too soon to blame him.
IIRC, it was a Taliban leader who recently publicly vowed to kill her. She replied that she would not be intimidated.
It seems to me that Musharef would almost have to have had prior knowledge, given his recent actions against Bhutto.
It'll be interesting to see how Musharef handles this and also how India reacts. I don't see how anything good can come out of this.....
