September 11 attacks
The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage. Additional people died of 9/11-related cancer and respiratory diseases in the months and years following the attacks.

The assassination of Massoud is believed to have a connection to the September 11 attacks on US soil, which killed nearly 3000 people, and which appeared to be the terrorist attack that Massoud had warned against in his speech to the European Parliament several months earlier. John P. O'Neill was a counter-terrorism expert and the Assistant Director of the FBI until late 2001. He retired from the FBI and was offered the position of director of security at the World Trade Center (WTC). He took the job at the WTC two weeks before 9/11. On 10 September 2001, O'Neill told two of his friends, "We're due. And we're due for something big. ... Some things have happened in Afghanistan. [referring to the assassination of Massoud] I don't like the way things are lining up in Afghanistan. ... I sense a shift, and I think things are going to happen ... soon." O'Neill died on 11 September 2001, when the South Tower collapsed.
