GWEN IFILL:

The brutal tactics of Islamic State radicals reached a grisly new extreme today. The group put out a video showing a captured Jordanian pilot being burned alive.

In Washington, the visiting king of Jordan rearranged his schedule to meet with President Obama this evening, while, back home, his people absorbed the shock.

The pilot's father was attending a tribal meeting with other relatives in Jordan's capital when the video surfaced. He checked his cell phone, hung his head, and left. Then, a government spokesman confirmed the news publicly.
