Firefighters and other first responders gathered outside Fire Station Five early Sunday morning.
The bells rang at 6:59 a.m. PST, the same time the south tower collapsed at the World Trade Center.
The tolling of the bells is a firefighter tradition to remember the people who died on Sept. 11, 2001.
"When you're a firefighter and you're going down the street, there are things that go through your mind," said Tim Szymanski from Las Vegas Fire & Rescue. "I can imagine what they were thinking when they were going out to the World Trade Center."
The 9/11 tribute included the raising of a special flag presented by the New York City Fire Department. Firefighters have special orders to fly it only on Sept. 11 at half-staff over a piece of metal from the World Trade Center.
Later in the evening, the Las Vegas Firefighters Benefit Association honored 9/11 victims with a march down Fremont Street. The parade ended at the 3rd Street Stage, where Las Vegas performer Frankie Scinta sang the National Anthem.
Other local figures also paid tribute to the Sept. 11 victims.
Nevada Senator Harry Reid put out the following statement:
The memory of that terrible day will never fade, and the many innocent lives lost will never be forgotten. We lost 2,977 Americans that day. But we didn’t allow terror to break us. We rose again together – stronger and more determined than ever.
Meanwhile, the North Las Vegas Police Department tweeted the following:
