During the September 11, 2001 attacks, 2,977 people were killed, 19 hijackers committed murder–suicide, and more than 6,000 others were injured. Of the 2,996 total deaths (including the terrorists), 2,763 were in the World Trade Center and the surrounding area, 189 were at the Pentagon, and 44 were in Pennsylvania. These deaths included 265 on the four planes. The attacks remain the deadliest terrorist act in world history.Most of those who perished were civilians except for 343 members of the New York City Fire Department and 71 law enforcement officers who died in the World Trade Center and on the ground in New York City; a United States Fish and Wildlife Service Office of Law Enforcement officer who died when United Airlines Flight 93 crashed into a field near Shanksville, Pennsylvania; 55 military personnel who died at the Pentagon in Arlington County, Virginia; and the 19 terrorists who died on board the four aircraft. At least 102 countries lost citizens in the attacks.A total of 2,750 victims were confirmed to have died in the initial attacks at the World Trade Center site. 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.As of August 2013 medical authorities concluded that 1,140 people who worked, lived, or studied in Lower Manhattan at the time of the attack have been diagnosed with cancer as a result of "exposure to toxins at Ground Zero". In September 2014, it was reported that over 1,400 9/11 rescue workers who responded to the scene in the days and months after the attacks had since died. At least 10 pregnancies were lost as a result of 9/11. Neither the FBI nor New York City officially recorded the casualties of the 9/11 attacks in their crime statistics for 2001, with the FBI stating in a disclaimer that "the number of deaths is so great that combining it with the traditional crime statistics will have an outlier effect that falsely skews all types of measurements in the program's analyses."
