As Al-Qaeda claimed, although Mehsud has denied any involvement. "CIA boss names Bhutto's killers," from the BBC (thanks to the Constantinopolitan Irredentist):
The CIA has added its support to the view that a Pakistani militant, Baitullah Mehsud, and al-Qaeda organised Benazir Bhutto's killing.
CIA Director Michael Hayden told the Washington Post that the former Pakistani prime minister was killed by fighters allied to Baitullah Mehsud.
The Pakistani government accused Mehsud of the attack shortly after Ms Bhutto's death in Rawalpindi on 27 December.
Mr Hayden did not reveal the sources for his claim.
Correspondents say that Mr Hayden's comments are the most comprehensive public assessment by US intelligence of Ms Bhutto's death.
