Dr Clive Williams, director of terrorism studies at the Australian National University, says documents provided by an Indian colleague suggested bin Laden died of massive organ failure in April last year. "It does seem reasonably convincing based on the evidence that I've been provided with that he's certainly either severely incapacitated or dead at this stage," Dr Williams said. Dr Williams said Ayman al-Zawahiri, bin Laden's deputy who was the target of a US air strike in Pakistan last week, has been making all statements on behalf of the terror network for the past year. Dr Williams said proving whether the terrorist leader was still alive might be impossible. "It's hard to prove or disprove these things because there hasn't really been anything that allows you to make a judgment one way or the other," Dr Williams said. "But it does seem strange that Dr Zawahiri has been making all of the statements since then, and nothing's been heard from bin Laden since, I think, the December of the year before." Dr Williams said even if bin Laden was dead, those who upheld the same philosophies would continue to fight for their cause.
