The Anatomy of the Attack on Bhutto
Bill Roggio describes the attempt on Benazir Bhutto, which may have included attacks to breach the police cordon prior to going for the primary.
Bhutto herself said there were two suicide bombers involved in the attacks, while there were four suicide squads sent to kill her. "There was one suicide squad from the Taliban elements, one suicide squad from al Qaeda, one suicide squad from Pakistani Taliban and a fourth — a group — I believe from Karachi," she said. Bhutto also stated street lamps went dark as the procession moved through Karachi at midnight.
The bombings were also coordinated with sniper fire. "After the explosions, Bhutto's supporters reported hearing gunshots, and there were three indentations in the glass screen of her truck that appeared to have been caused by bullets," The New York Times reported.
It is clear this was a sophisticated, professional strike planned in advance. "It is a pattern that would suggest the attack was planned meticulously and conducted expertly, certainly not by a novice," Karachi's chief of police said.
Bill Roggio notes, "The assassination attempt against Bhutto bear the hallmark of the past al Qaeda attempts to assassinate President Musharraf."
The attempts on Musharraf's life have featured attacks on his motorcade, including suicide vehicles ramming to penetrate the security cordon. Although the blasts were attributed to al-Qaeda, a soldier from the Pakistani military was also involved. Interestingly, two attempts were made on Musharraf in rapid succession which may imply that a fallback plan against Bhutto may exist.
