Did Charlie Hebdo die in vain?
Referring to last week's shocking events, French Prime Minister Manuel Valls said his country was at war with extremism and terrorism - but not with Muslims.
He was speaking on Tuesday after funeral ceremonies were held for seven of the victims in France and Israel.
France has deployed 10,000 troops at various sites across the country - including synagogues, mosques and airports - in response to the attacks.
Meanwhile, controversial French comedian Dieudonne M'bala M'bala was arrested on Wednesday for "defending terrorism".
Police opened an investigation into the comic on Monday, after he wrote on a Facebook post "I feel like Charlie Coulibaly" - merging Charlie Hebdo with the name of supermarket gunman Amedy Coulibaly.
