Middle Tennessee honored first responders who were killed on 9/11 as Monday marked 16 years since the terror attacks.
In the 2001 attack, 19 men hijacked four US commercial airplanes. A total of 2,977 people were killed in New York City, Washington, DC, and outside of Shanksville, Pennsylvania.
The Nashville Fire Department, along with city leaders that included Mayor Megan Barry, commemorated the lives lost at the Fallen Firefighters Memorial at the Schermerhorn Symphony Center.
"On September 11, 2001, thousands of firefighters and first responders ran towards unimaginable danger knowing it might be the last thing they would ever do," said Mayor Megan Barry. "Every day, our first responders are ready and willing to put their lives on the line to keep us safe.”
During the ceremony, they read the names of Nashville Fire Department personnel who have passed away since last September.
Further south in Franklin, officials also held a ceremony outside of police headquarters. First responders and firefighters paid tribute to the many who lost their lives on that tragic day.
Earlier Monday morning, President Trump observed a moment of silence on the White House South Lawn to mark the moment the first plane hit the World Trade Center.
