John Brennan, the director of the CIA, put American and the world on alert Monday for more ISIS attacks in the "short term."

In a CBS "This Morning" interview, the nation's intelligence chief said, "I think ISIS' capability to carry attacks outside of the Syria and Iraq will continue and could increase."

He added, "Could increase in the short term."

The interview came before the attacks over the weekend in Minnesota or New York.

Brennan said that the ISIS attacks around the world are the product of investments by the terror group.

He said, "They have invested in this over the past several years. And right now I think they are trying to reap the harvest of those investments."
