The ceremony was held at Central Fire Station before a large audience, including Lamar Elementary school children.
Firefighter James Fisher rang the fire bell in the traditional signal when a firefighter is killed in the line of duty.
Bagpiper Jean E. Orcutt played "Amazing Grace."
Prayers were offered by representatives from the Meridian fire and police departments, the U.S. military, emergency medical services and the Lauderdale County Sheriff's Department, followed by a community prayer delivered by the Rev. Elvin Sunds of St. Patrick Catholic Church.
"Almighty God, we pray that today's remembrance of the tragedy of Sept. 11, 2001, will renew our resolve to work for peace in our world, in our communities, in our families, and in our hearts," said Sunds. "We remember those killed and those injured one year ago today."
Meridian Fire Chief Bunky Partridge then came forward.
"May we all bow for a moment of silence to remember the families, the lost loved ones in Washington, Pennsylvania and New York City?" said Partridge.
Those assembled recited the Pledge of Allegiance. Taps was played by a lone trumpeter, as a large American flag was unfurled from the fire station's upper balcony.
