Libya's acting prime minister, Mahmoud Jibril, believes former dictator Muammar Gaddafi should not have been killed and instead should have been put on trial for his crimes, Jibril said in a BBC interview.

Gaddafi's body remained on public display in a cold storage container in Misrata, bearing wounds assumed to have been inflicted by fighters who hauled him from a drain in his hometown of Sirte.

"To be honest with you, at the personal level, I wish he was alive. I want to know why he did this to the Libyan people," the BBC quoted Jibril as saying on Sunday. "I wish I were his prosecutor in his trial, you know," he added. "Because this is the question which is in everybody's mind: Why? Did the Libyan people deserve what he did throughout 42 years of oppression, of killing, of everything?"

United Nations High Commissioner for Human Rights Navi Pillay has called for an investigation into the killing of the ex-leader. In response to this, Jibril said that it would be "absolutely OK" to carry out a full investigation into the killing under international supervision as long as Islamic burial rules were respected, the BBC reported. The United States said accounting for Gaddafi's death should be done in an "open and transparent manner."

Jibril also said there had been "some limited violations of human rights" during Libya's revolution. In addition, he suggested Libya's interim authorities might welcome continued support from NATO beyond the end of October, when it plans to conclude its air campaign.
