Sunday marks the tenth anniversary of the September 11 attacks, and people from all across  Chicagoland are remembering and honoring those who lost their lives that day.

Flags around the city all flew at half mass as Chicago remembers the 10th Anniversary of the 9/11 terrorist attacks.

Hanging from the Wrigley Building in downtown Chicago was a large American flag.

At noon Sunday in Chicago, the firefighters at the firehouse on Dearborn and Illinois, Engine 42 and Truck 3, pay a tribute to those who lost their lives on 9/11/2001. Fire trucks sounded their sirens for a moment and flashed their lights as firefighters saluted and lowered their heads in a moment of silence to remember their fallen comrades.

We will never forget!
