CIA Director John Brennan said Monday the deadly attacks in Paris that killed 129 people are not "a one-off event" and that intelligence agencies in Europe and elsewhere are likely redoubling efforts to uncover terror plots, NBC News reported.
"I certainly would not consider it a one-off event. It is clear to me that ISIS has an external agenda and that they are determined to carry out these types of attacks," Brennan told a gathering of policy experts at the Center for Strategic and International Studies in Washington. "This was not something done in a matter of days. This was something that was deliberately and carefully."
Brennan's comments came hours after French police launched a huge manhunt in the wake of the attacks in Paris. Prime Minister Manuel Valls told the RTL radio more than 150 raids were carried out across the country. Interior Minister Bernard Cazeneuve said that 23 people had been arrested — while 104 others remained for questioning — over a 48-hour period. He added that guns, bulletproof vests and even a rocket launcher had been seized.
