"We are at war with terrorism," he told the station. "The terrorists can strike again."

Interior Minister Bernard Cazeneuve said that 23 people had been arrested — while 104 others detained for questioning — over a 48-hour period. He added that guns, bulletproof vests and even a rocket launcher had been seized.

"This is just the beginning," Cazeneuve said. "The response of France will be total. Those who attack France, we will catch them and we will be unrelenting with them ... Terrorists will never destroy the Republic, because the Republic will destroy them."

A total of 168 raids took place throughout the country, including some in the cities of Toulouse, Grenoble, Bobigny and Lyon.

They came amid a broadening investigation that has stretched across Europe to find any potential accomplices to the bloody attacks which rocked Paris on Friday.

Three teams of terrorists laid siege to Paris on Friday night, killing 129 people in a spree of shootings and explosions across six locations. The attackers were all outfitted with suicide vests and armed with Kalashnikovs.

French President Francois Hollande called the attacks — which ISIS claimed responsibility for — an “act of war” and on Sunday night launched airstrikes on the terror group’s de facto capital of Raqqa, Syria.

Hollande also asked the country's parliament to extend the state of emergency for a three-month period and announced plans for 5,000 new police and military posts to be created in the next two years.

In an address to France's Congress, Hollande warned that jihadist terror "threatens the entire world."

Authorities also expanded a massive manhunt for any potential accomplices — with one Salah Abdeslam in the crosshairs.

An arrest warrant described the 26-year-old him as “dangerous” and potentially linked to the attacks. NBC News learned that Abdeslam signed the rental car papers for one of the cars used by the attackers.

One of his brothers is reportedly among the dead attackers.

French authorities released more information on two of the other terrorists on Monday.
