France paid tribute to the journalists, police officers and shoppers at a kosher supermarket in Paris killed two years ago by Islamist terrorists, the first of a wave of terror attacks that has left more than 230 dead and triggered a state of emergency.

Police, ministers and Paris’ mayor stood in silence outside the old office of the Charlie Hebdo magazine and other sites as floral wreaths were laid to mark the anniversary.

The tributes started at the old premises of the magazine, since abandoned for a secret location. There two terrorists Said and Cherif KOuachi armed with assault rifles shot and killed 11 people on Jan. 7, 2015, including most of the notoriously irreverent publication’s cartoonists and writers.

Homage was then paid at the nearby site where a policeman was shot dead at point-blank range by one of the two gunmen.

The Charlie Hebdo attack was followed a day later by the killing of a trainee policewoman by Amedy Coulibaly, an Islamic State terrorist. The following day he attacked Jewish supermarket Hyper Cacher on Porte de Vincennes in Paris, where he murdered four hostages, before police killed him. On Monday, the Jewish community will organize a ceremony at the supermarket to mark the seconf anniversary of the attack in presence of the victims’ families and those who were taken as hostages.

In all, seventeen people were killed in the Charlie Hebdo and Hyper Cacher store attacks.

The killing spree preceded further terror attacks in Paris. In November 2015 suicide bombers and gunmen struck venues across Paris, killing 130 people. Last year a Tunisian who pledged allegiance to the Islamic State terror group plowed his truck through a crowd in the Mediterranean city of Nice, killing 86 people.
