The September 11 attacks were a tragedy for the United States and its allies, but they also caused many deaths around the world.
According to the book “The Death Toll: The 9/11 Attack on America” by Richard Miniter, 2,996 people were killed in the 9/11 attacks. Of those, 2,606 people were killed at the World Trade Center site, 147 people were working in those towers when they collapsed, 125 people were killed at the Pentagon (including military personnel), 40 people were killed when Flight 93 crashed into a field near Shanksville, Pennsylvania—and 19 hijackers were also killed in these attacks. More than 90 countries lost citizens in these attacks as well.
As of September 11, 2018, 2,753 people have died as a result of the September 11 attacks. The number of people who have died from 9/11-related illnesses is also rising—more than 400 rescue workers and first responders have died from cancers and respiratory diseases related to their work after September 11th. This includes military personnel killed in subsequent wars in Afghanistan and Iraq following September 11th as well as those who worked on rescue efforts during this time period.
