WASHINGTON, Dec. 28 (UPI) -- Benazir Bhutto reportedly wrote a U.S. friend Oct. 26 Pakistan President Pervez Musharraf would be partly to blame if she was killed, which occurred Thursday.

In the Oct. 26 e-mail, the former two-time Prime Minister, assassinated at a Rawalpindi political rally, mentioned Musharraf also should be held responsible if she were to die, CNN reported Friday.

The e-mail reportedly was written to Mark Siegel, Bhutto's U.S. spokesman, lobbyist and friend. The report said Siegel sent the message to correspondent Wolf Blitzer with instruction the contents not be aired unless Bhutto was killed.

Bhutto escaped a suicide bomb attack Oct. 18 on her motorcade in Karachi where thousands had gathered to welcome her return from an eight-year self-imposed exile in Dubai. The attack killed about 140 people.

Her return had been facilitated by Musharraf. But in her e-mail she had complained of inadequate security.

"Nothing will, God willing happen," she wrote Siegel. "Just wanted u to know if it does in addition to the names in my letter to Musharaf of Oct 16nth, I wld hold Musharaf responsible. I have been made to feel insecure by his minions …"

Pakistan's U.S. ambassador Mahmud Ali Durrani has said Musharraf's government provided Bhutto with unprecedented security.

Speaking to CNN's The Situation Room, Siegel also said, "She was moving almost in a sea of humanity. No system in the world can protect you against that."
