December 2001 Quoting an unnamed Taliban official, the Pakistan Observer reported that Bin Laden died of untreated lung complications and was buried in an unmarked grave in Tora Bora on December 15. This report was picked up by Fox News in the United States on December 26. Also on December 26, the Egyptian newspaper AlWafd - Daily carried a short obituary by a prominent official of the Afghan Taliban, who was allegedly present at the funeral, stating Bin Laden had been buried on or about December 13:
"(Osama bin Laden) suffered serious complications and died a natural, quiet death. He was buried in Tora Bora, a funeral attended by 30 Al Qaeda fighters, close members of his family and friends from the Taliban. By the Wahhabi tradition, no mark was left on the grave"
A videotape was released on December 27 showing a gaunt, unwell Bin Laden, prompting an unnamed White House aide to comment that it could have been made shortly before his death. On CNN, Dr Sanjay Gupta commented that Bin Laden's left arm never moved during the video, suggesting a recent stroke and possibly a symptom of kidney failure. According to Pakistani President Musharraf, Bin Laden required two dialysis machines, which also suggests kidney failure. "I think now, frankly, he is dead for the reason he is a... kidney patient," Musharraf said. If Bin Laden suffered kidney failure, he would require a sterile environment, electricity, and continuous attention by a team of specialists, Gupta said. In April 2002, U.S. Defense Secretary Donald Rumsfeld stated, "We have heard neither hide nor hair of him since, oh, about December in terms of anything hard." FBI Counterterrorism chief Dale Watson and President Karzai of Afghanistan also expressed the opinion that Bin Laden probably died at this time.
October 2002: In a CNN interview, Afghan President Hamid Karzai stated that "I would come to believe that [bin Laden] probably is dead."
April 2005: The Sydney Morning Herald stated "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'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."
