Twenty-five years after the United States was attacked by terrorists on Sept. 11, 2001, remembrance ceremonies are scheduled to take place across the country at locations where nearly 3,000 people died in the attacks.
Approximately 2,977 people died on Sept. 11, 2001. Among them, 2,753 died at the World Trade Center, 184 died at the Pentagon in Arlington, Virginia, and 40 passengers and crew members died aboard a hijacked plane that crashed in Shanksville, Pennsylvania.
Additionally, thousands of first responders, recovery workers and survivors have died since the attacks from illnesses linked to exposure to toxins from debris at Ground Zero and other sites. The 9/11 Memorial & Museum says thousands have died from 9/11-related illnesses.
The 25th
anniversary World Trade Center memorial ceremony will be livestreamed Friday.
What happened on Sept. 11, 2001?
On the morning of Sept. 11, 2001, terrorists hijacked four passenger planes and crashed them into several United States landmarks, including the Twin Towers at the World Trade Center in New York City and the Pentagon in Arlington, Virginia.
The fourth plane crashed into an empty field in Shanksville, Pennsylvania, after passengers tried to take control of the plane to prevent it from crashing into another "important symbol of democracy and freedom."
Overall, 2,977 people died in the attacks. In the years since 9/11, thousands of first responders, recovery workers and survivors have died from illnesses related to exposure to toxins from the attacks.
Thousands more continue to deal with 9/11-related health conditions. The World Trade Center Health Program provides monitoring and treatment for people with certified 9/11-related health conditions.
