The then Pakistan President Pervez Musharraf was responsible for the murder of his mother and former prime minister Benazir Bhutto, her son and Pakistan Peoples Party chairman Bilawal Bhutto Zardari has said.

"He (Musharraf) murdered my mother (Benazir Bhutto). I hold him responsible for the murder of my mother," Bilawal Bhutto told the CNN in an interview.

When asked why he was saying so, he said, "Because he (Musharraf) was aware of the threats. He himself had threatened her in the past'.
