Islamabad: Pakistan Peoples Party (PPP) Chairman Bilawal Bhutto on Wednesday branded former President Pervez Musharraf as the "killer" of his mother Benazir Bhutto as the country observed her 10th death anniversary. Reiterating that he holds the man who pulled her security rather than the man who pulled the trigger responsible for his mother's death, Bilawal Bhutto raised the "Musharraf's a murderer!" slogan in front of the charged crowd of PPP supporters in Garhi Khuda Bakhsh, Dawn online reported.
