Antalya, Turkey (CNN)ISIS probably has plans for more attacks "in the pipeline," according to the head of the CIA, although President Barack Obama's national security team said over the weekend that the threat to Europe is greater than it is to the U.S.
"I certainly would not consider it a one-off event," said CIA Director John Brennan, speaking at a Center for Strategic and International Studies forum in Washington on Monday.
"It is clear to me that ISIL has an external agenda, that they are determined to carry out these types of attacks," he continued, using another term for ISIS. "This is not something that was done in a matter of days. This was carefully planned over the course I think of several months, in terms of making (sure) they had the operatives, the weapons and the explosives with the suicide belts."
