An event commemorating the first anniversary of the murder of four Jews, Yoav Hattab, Yohan Cohen, Francois-Michel Saada and Philippe Braham, by an Islamist terrorist, Amedy Coulibaly, in a kosher supermarket in Paris will take place on January 9.

This commemoration is organised by CRIF, the umbrella representative group of French Jewish organisations which called on the general public to attend it.

It will take place at the HyperCacher supermarket in eastern Paris. The event is also meant to commemorate the 13 people who died in terrorist attacks committed by Islamists on January 7 and 8.

“Let us show up in large numbers to honor the memory of the 17 victims of the January killings,” CRIF wrote. The Hyper Cacher murders followed the slaying of a police officer the previous day by the same shooter and the killing of 12 the day before that at the office of the Charlie Hebdo satirical magazine.

In a statement, CRIF said: “A year has passed, a testing year for France, for all those affected by terrorist fanaticism. We will never forget the terrible month of January 2015, for which a whole nation mourned. In this context, CRIF, with the participation of the authorities, is organizing a gathering of unity and republican values.’’

French Jewish philosopher Bernard-Henri Levy said that attendance at CRIF’s commemoration events for the Hyper Cacher killings’ anniversary will be a “test for France.”

On Tuesday, French President Francois Hollande kicked off a week of commemorations marking the January 2015 Paris jihadist rampage ;

Flanked by Paris Mayor Anne Hidalgo, the French leader unveiled a plaque at Charlie Hebdo's former offices.

The January 7-9, 2015, attacks by brothers Said and Cherif Kouachi, dubbed "France's 9/11", marked the start of a string of jihadist strikes in the country that culminated in the November 13 attacks in Paris that left 130 dead.

The massacre at Charlie Hebdo unleashed an outpouring of solidarity for freedom of expression, with the rallying cry "Je Suis Charlie" taken up around the world.

Hollande went on to unveil a third plaque at the Hyper Cacher, a kosher supermarket in an eastern suburb where four Jews — three shoppers and an employee — were killed during a horrifying hostage drama.

The president greeted Lassana Bathily, the Muslim worker at the supermarket credited with saving many shoppers' lives by helping them hide in the store's underground cold room and later aiding police in the logistics of their raid.

Hollande will return to the supermarket on Saturday for the ceremony organized by CRIF.
