He said they would reappear as the trial of alleged accomplices of three men involved in the attack begins.
Some of the magazine’s best-known cartoonists were among the 12 people killed when Said and Cherif Kouachi opened fire in his offices.
The brothers and an acquaintance of them from the prison, who killed five people within 48 hours of the Charlie Hebdo massacre, were eventually gunned down by police in separate clashes.
