A day after the Islamic State released a video showing a Jordanian pilot being burned alive, Jordan launched airstrikes against the group in Iraq that killed 55 people, including a top commander known as the "Prince of Nineveh," Iraqi media reported Wednesday. The airstrikes came just hours after Jordan's King Abdullah II pledged a "severe" response.
