The stage is lit in the colors of the French flag during a concert to thank the anonymous "heroes"

Some 12,000 emergency and health workers, security officials and others who jumped in to respond to the November 13 terror attacks in France were honoured at a concert Monday in Paris.

"Firefighters of Paris, doctors, surgeons, police forces, soldiers, rescue workers," entertainer Nikos Aliagas addressed the crowd, adding several other categories of workers such as bomb experts to the list, calling them the "humble heroes of our country".

"We are proud of you and we express our gratitude," he said.

Paris Mayor Anne Hidalgo told the gathering: "On the cusp of this new year, I want to share with you my confidence and tell you the pride I feel working alongside you. Paris is very lucky to be able to count on you. We will never forget it."

The coordinated series of gun and bomb attacks at several sites in Paris, including the Bataclan concert hall, left 130 dead.

Interior Minister Bernard Cazeneuve and Health Minister Marisol Touraine also attended the event, as well as the head of Paris hospitals, Martin Hirsch.

The stage then was given over to singers including Zaz, Benabar and Jane, before the hall burst into an improvised rendition of "La Marseillaise" a cappella.

The broadcast was viewed by some three million people nationwide.
