French President Emmanuel Macron said on Tuesday that the October 7 attack by Hamas against Israel was the “biggest” anti-Semitic massacre of our century as he presided over a ceremony honoring the victims.

The ceremony was held at the Invalides Memorial in Paris and commemorated the 42 French citizens killed in the attack, as well as three others who are still missing and believed to be held as hostages.

Macron said the attack was "barbarism, which is fed by anti-Semitism and propagates it.”

Some of the victims’ families were brought to France on a special flight to attend the ceremony, where victims were represented with a photograph.

There were also 42 empty chairs at the ceremony to depict the victims’ presence. Macron confirmed France’s commitment to rescue the three French citizens presumed to be hostages.

Representatives from Israel’s embassy attended the ceremony in place of President Isaac Herzog, who was unable to be present.

About 1,160 people, the majority civilians, were killed in the October 7 attack, and 250 hostages were captured. Israel says 132 remain in Gaza, and at least 28 have been killed.
