President Obama says the U.S. will remain aggressive in its efforts to defeat ISIS and is counting on the world's support.

FOX's Gurnal Scott has the story:

Standing with Argentinian President Mauricio Macri, President Obama says world forces must continue to pursue ISIS:

(President Obama) "Until it is removed from Syria and removed from Iraq and is finally destroyed."

The President's comments came in response to the deadly Brussels attack, for which ISIS has claimed responsibility. He says while the ultimate goal is their destruction, diminishing their influence on the world will lead to that:

(President Obama) "We are strong. Our values are right. You offer nothing except death." 

He says the world must be united against terrorism.
