Nearly 3,000 people died on Sept. 11, 2001 when terrorists hijacked four commercial planes and crashed them in New York City, Washington D.C. and Stonycreek Township, Pennsylvania.

And 17 years later, people across the United States are remembering and honoring those who perished in the attacks.

Around metro Atlanta on Tuesday there are memorial services, commemorations and tributes planned for the anniversary.

Mayor Lori Henry, police chief Rusty Grant and fire chief Ricky Burnette will also speak.
