"According to existing information, brothers Kouachi were known to the French special services – they had fought in Syria for the Islamic State [IS] terrorist organization. Then they recruited people in France for this war. French special services did not control them in any way and did not react to this," Goncharov said Friday.
"These criminals were well-prepared. They studied the work of this editorial office, the people who worked there, and killed those they deemed enemies of their religion. So I would not speak of a positive work on the part of French special services in this case," Goncharov told RIA Novosti.
The attack on the Charlie Hebdo satirical magazine took place on January 7, after a caricature of the IS leader appeared on its Twitter page.
On Thursday, US officials stated that Said had traveled to Yemen and had direct contacts with al-Qaeda.
The French Charlie Hebdo magazine had received several threats from radical Islamists over its publication of caricatures of prophet Muhammad in the past.
