"Of course this attack has been perpetrated by Muslim fundamentalists… Unfortunately this is a result of the expansion of Islam inside France, because the government… has put up no resistance against the expansion of radical Islam in France over the last decade," Chauprade said, adding that the attack is the result of a "lack of responsibility from the French government."
Chauprade, who is a member of the right-wing National Front party, emphasized that the terrorism threat in France is high with non-governmental radical organizations promoting Sharia law and Muslim values instead of French ones.
"We have to stop the expansion of all these radical organizations that are building mosques, that are trying to impose Sharia law instead of the law of the French Republic, and we have to be very strong and very firm against this threat," Chauprade said.
The member of the European parliament also said that there are a high number of Islamic State fighters inside France and Europe's Schengen Area in general, and so it is not only France that faces the danger of attacks by radicalized Muslims, but other European states too.
Chauprade emphasized the need for Europe's cooperation with Russia to fight the spread of Islamic radicalism.
"We also have to cooperate more with Russia instead of pressuring Russia about Ukraine. We should work with Russia to fight against terrorism. Because we are all in the same war against fundamentalism and radical Islam," he argued.
On Wednesday, three gunmen entered the central Paris office of the Charlie Hebdo satirical magazine, shooting and killing 12 people and injuring several others, while reportedly shouting "Allah Akbar." The killers evaded capture at the scene and remain at large.
President of France Francois Hollande said that French authorities would track the perpetrators down regardless of how long it takes, with the massive search operation already underway.
The magazine has been threatened previously by radical Islamists for publishing caricatures of the prophet Muhammad and other controversial cartoons.
Among the latest posts on Charlie Hebdo's Twitter was a cartoon mocking the leader of Islamic State militant group Abu Bakr Baghdadi.
