Fenech warned that France may soon face a large influx of those returning from the wars in Iraq and Syria because the terrorist group Daesh (ISIS/ISIL/Islamic State) is losing its territories and its collapse is just a matter of time.
"Guantanamo a la Francais would be the simplest solution. Designed for incarcerating radicalized people, the facility would be an effective option," he said.
According to data announced by French Prime Minister Manuel Valls in the French parliament earlier this month, a total of 2,147 French nationals are involved in the wars in Syria and Iraq, with more than 1,000 of them still in these countries and 203 already returning to France.
In last year's interview with Sputnik, French politician Nicolas Dupont-Aignan also stressed the necessity of building a "Gitmo-like prison" in order to isolate French citizens involved in terrorist acts.
The prison at Guantanamo Bay in Cuba is designed for the detention of persons suspected or accused of terrorism after the 9/11 attacks, which claimed the lives of almost 3,000 people.
American and international rights activists had repeatedly criticized the Bush administration for serious violations of human rights in relation to Guantanamo detainees, including torture and holding people who haven't been charged with committing a crime.
The French parliamentary commission on terrorism was formed to assess the nation's failure to prevent a series of terror attacks in Paris which left a total of 147 people dead in November, 2015.
These included a series of bomb attacks outside the national sports stadium and at a rock concert at the Bataclan concert hall on November 13, which left at least 130 people killed and 360 more injured.
