"The city is again holding this walk to honor the memory of the people who perished in the 9/11 attacks and to recognize the first-responders and members of the armed forces who are protecting our safety and well-being," Hannemann said in a news release.

"This is an occasion for Honolulu to remember the losses we suffered and the acts of heroism summoned the day of the attacks."

The public is invited to participate in the walk, which includes brief ceremonies and wreath presentations at the Honolulu Police Department headquarters and Honolulu Fire Department headquarters, a moment of silence at the Prince Kuhio Federal Building, and the formal program at Honolulu Hale.
