European intelligence agencies are overwhelmed by suspects linked to Islamic State and are struggling to clamp down on a black market in military assault rifles, CIA Director John O. Brennan said Monday.
In London, Prime Minister David Cameron said Monday his government plans to recruit an additional 1,900 intelligence officers to work for its intelligence agents.
The British and other allied spy services in Europe face “an overwhelming number of cases they need to pursue,” Brennan told a security forum at the nonpartisan Center for Strategic & International Studies think tank in Washington.
Thousands of Europeans have joined terrorist groups in Iraq and Syria, raising fears they could come back and launch terrorist attacks in their home countries. Brennan warned that the coordinated attacks in Paris are not a “one-off event” and that Islamic State has other attacks planned.
“I would anticipate this is not the only operation ISIL has in the pipeline right now,” Brennan said, using an alternative acronym for Islamic State.
A purported Islamic State video was released Monday that warned more terrorist attacks are coming in Europe, and specifically threatened to launch an attack in Washington.
