Both the country's prime minister and interior minister have already blasted the brutal assault, which happened on Monday in the Paris suburb of Creteil, as "anti-Semitic."
And yesterday, Hollande said these types of violent tragedies did not only hurt the families but that "it's the best of France that finds itself hurt, broken."
He said the assault showed that "evil sweeps through our societies" and denounced "a form of violence all the more unbearable because it aims to divide."

Police spotted the three alleged assailants soon after Monday's attack, and while two of them were detained in possession of stolen jewelry -- and subsequently recognised by the victims -- the third is on the run.
The two allegedly involved in the attack have also been charged with gang rape, armed robbery, kidnapping and extortion.
The accused are also suspected of having beaten a Jewish man in his 70s in November.
But a lawyer for one of the suspects said the interior ministry had reacted prematurely and condemned the "media frenzy" surrounding the case.
