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 do n'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
