The red line: World waits for US reaction to strike on its forces in Jordan

On Deadline today is looking at the possibility of an expanded war in the Middle East, after a drone strike killed three US service members in Jordan, and left dozens injured. Officials believe the attacks were from pro-Iranian militias, but they are still working to determine exactly who launched the drone and from where it launched. In the meantime, the Middle East conflict is becoming multi-pronged for US forces. On Deadline is hosted and produced by Lauren Barry.
