ISIS "Second in Command" Killed by US Forces in Syria

US Special Forces believe they've killed a senior leader of the Islamic State of Syria and Iraq, said to be second in charge. Defense Secretary Ash Carter told a news conference that it's a sign of progress. "We're certainly gathering momentum and seeing that momentum having an effect… who's who in ISIL so we can kill them."
