Ash Carter: US Looking for Opportunities to Strike ISIS

The United States continues to look for opportunities to strike at the Islamic State, Defense Secretary Ash Carter said on Monday.

"We're looking for opportunities to get at them, and we'll continue to do that until they're defeated," Carter said, in comments made during his first public appearance since coordinated attacks in Paris on Friday.

Those methods include strikes on oil infrastructure and identifying and aiding ground forces, Carter said in a forum hosted by the Wall Street Journal shown online.
