Casualties of the September 11 attacks
2,974 victims were confirmed to have died in the initial attacks; this includes Sneha Anne Philip, a doctor, who in 2008 was ruled to have died on 9/11. In 2007, the New York City medical examiner's office began to add people who died of illnesses caused by exposure to dust from the site to the official death toll. The first such victim was a woman, a civil rights lawyer, who had died from a chronic lung condition in February 2002. In September 2009, the office added a man who died in October 2008, and in 2011, a male accountant who had died in December 2010. This raises the number of victims at the World Trade Center site to 2,753, and the overall 9/11 death toll to 2,996.
History of New York City (1978–present)
On September 11, 2001, Islamic terrorist hijackers linked to the jihadist organization Al-Qaeda piloted two hijacked passenger airliners into each of the twin 110 story World Trade Center towers. The airplanes, designated for transcontinental flights and therefore fully loaded with jet fuel, were hijacked mid-flight and intentionally crashed into the towers in the early morning hours of September 11. The crashes caused massive structural damage during impact, ripping gaping holes into the towers, and ignited raging fires, that caused both weakened towers to collapse in less than two hours. Together with a simultaneous attack on the Pentagon in Arlington, Virginia, and a failed plane hijacking that resulted in a plane crash in Shanksville, Pennsylvania, 2,977 victims died in the attacks.
