This is from this site. It is not surprising that Bhutto was killed.
The accounts vary. Some say that she was first shot when she stuck the top of her body through her SUV to wave at the crowd. Immediately afterward there was a suicide bomber who badly damaged her vehicle.
Both the extreme Islamists and some in the government wanted her dead. Al Qaeda probably did it but just claiming responsibility doesn't clinch the matter. Both Musharraf and the US want to blame it on Al Qaeda of course. Bhutto was widely seen as the US candidate for president and that did not help her at all. Sharif's party also experienced attacks on a rally that killed several people.
Bhutto certainly did not fear death but perhaps it would have been better if she had been more careful as is Musharraf. I am reminded of Aristotle's concept of courage as a mean between cowardice (too much fear of danger) and foolhardiness (too little fear of danger). Bhutto tended toward the foolhardiness end of the scale.
Pakistan: Al-Qaeda claims Bhutto's death
Karachi, 27 Dec. (AKI) - (by Syed Saleem Shahzad) - A spokesperson for the al-Qaeda terrorist network has claimed responsibility for the death on Thursday of former Pakistani prime minister Benazir Bhutto.
“We terminated the most precious American asset which vowed to defeat [the] mujahadeen,” Al-Qaeda’s commander and main spokesperson Mustafa Abu Al-Yazid told Adnkronos International (AKI) in a phone call from an unknown location, speaking in faltering English. Al-Yazid is the main al-Qaeda commander in Afghanistan.
It is believed that the decision to kill Bhutto, who is the leader of the opposition Pakistan People's Party (PPP), was made by al-Qaeda No. 2, the Egyptian doctor, Ayman al-Zawahiri in October.
Death squads were allegedly constituted for the mission and ultimately one cell comprising a defunct Lashkar-i-Jhangvi’s Punjabi volunteer succeeded in killing Bhutto.
Bhutto had just addressed a pre-election rally on Thursday in the garrison town of Rawalpindi when the bomb went off.
She had come to Rawalpindi after finishing a rapid election campaign, ahead of the January polls, in Pakistan's volatile North West Frontier Province (NWFP) where she had talked about a war against terrorism and al-Qaeda.
Reports say at least 15 other people were killed in the attack and several others injured.
As news of Bhutto's death spread throughout the country, there are reports that people have taken to the streets to protest the death of the leader of the PPP, which has the largest support of any party in Pakistan.
In the southern port city of Karachi, Bhutto's hometown, residents reportedly threw stones at cars and burnt tyres.
