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.
9/11 conspiracy theories
Some proponents of this believe that Jewish employees were forewarned by Israeli intelligence to skip work on September 11, resulting in no Jewish deaths at the World Trade Center. According to Cinnamon Stillwell, some 9/11 conspiracy theorists put this number as high as 4,000 Jewish people skipping work. This was first reported on September 17 by the Lebanese Hezbollah-owned satellite television channel Al-Manar and is believed to be based on the September 12 edition of "The Jerusalem Post" that said "The Foreign Ministry in Jerusalem has so far received the names of 4,000 Israelis believed to have been in the areas of the World Trade Center and the Pentagon at the time of the attacks."
