After surviving an assassination attempt in October, former Premier Benazir Bhutto had said President Pervez Musharraf would be responsible if any harm came to her as she was not being provided adequate security.
In an e-mail sent two months ago to her United States adviser and longtime friend, Bhutto cited Musharraf government's denial of her request for additional security measures after the October suicide bombing that targeted her upon returning from exile.
"Nothing will, God willing happen," she wrote to Mark Siegel, her US spokesman, lobbyist and friend.
Don't Miss: Why Bhutto is blaming who she is blaming
"Just wanted u (you) to know if it does in addition to the names in my letter to Musharaf of Oct 16nth, I wld (would) hold Musharaf responsible.
"I have been made to feel insecure by his minions and there is no way what is happening in terms of stopping me from taking private cars or using tinted windows or giving jammers or four police mobiles to cover all sides cld (could) happen without him."
Bhutto wrote the e-mail on October 26, eight days after at least 130 people were killed and hundreds wounded in Karachi by the suicide bombing on her homecoming motorcade.
Siegel forwarded that e-mail to CNN's Wolf Blitzer, with instructions he not report on it unless Bhutto was killed, the CNN said revealing the contents of the message.
In her letter to Musharraf, Bhutto had reportedly said there was a threat to her life from former chief minister Chaudhry Parvez Elahi, former ISI chief Hamid Gul, Hassan Afzal, former Deputy Chairman of the National Accountability Bureau (NAB), and Intelligence Bureau chief Brig (Retd) Ijaz Shah.
