“Our great and beautiful France will never break, will never yield, never bend,” he said in a ceremony at the Paris police headquarters on Tuesday.

“They died so that we could live in freedom.”

Victims of the second attack on a Jewish supermarket in Paris were also laid to rest in Jerusalem in an emotional ceremony with tight security.

Soldiers stood guard as Israeli Prime Minister Benjamin Netanyahu addressed the victims’ families and hundreds of other mourners who had travelled from France.

“When I hugged you in Paris, I said to you that I know your hurt — the hurt of fathers, of parents, boys and girls, sons and daughters, brothers and sisters, who have lost their dearest,” he said.

“And so, the people of Israel, the state of Israel, hug you with love in this dark day when four souls came to Jerusalem … the final resting place of Philippe, Yohan, Yoav and François-Michel.”

“May their souls rest in peace.”
