It also remains unclear who carried out the assassination. Pakistani President Pervez Musharraf has blamed Islamic militants, but several associates of Bhutto have accused Musharraf himself of having a role. In an email sent to a confidant in the US two months ago, Benazir Bhutto wrote that Musharraf should be held “responsible” if she was assassinated, because his government did not do enough to provide for her security. Bhutto survived another assassination attempt in October shortly after she returned from exile.
