Paris Attacks a 'Terrible, Sickening Setback' in ISIS Fight, Obama Says

President Obama has announced a new agreement to streamline intelligence sharing with France in the wake of the terror attacks in Paris, and appealed for more nations to "step up" to assist in the fight against ISIS.

"The terrible events in Paris were obviously a terrible and sickening setback," Obama said today in Turkey. "It reminds us that it will not be enough to take on ISIL in Iraq and Syria alone."
