ISIS news: Burns Jordanian pilot alive in video, Jordan vows 'punishment and revenge'

CAIRO/AMMAN — ISIS militants released a video Tuesday purporting to show Jordanian pilot First Lt. Muath al Kasasbeh being burnt alive while held captive in a cage. Jordanian state television said the pilot was actually killed Jan. 3, long before the terrorist organization demanded a prisoner swap for failed suicide bomber Sajida al-Rishawai.

The 22-minute clip was released by the al-Fuqan Media Foundation, the media arm of ISIS. The U.S. is working to verify the video's authenticity.

In the video, Kasaesbeh is interviewed while wearing an orange jumpsuit similar to other prisoners, and he described the mission he was due to carry out before his jet crashed in Syria in December. The incident made him the first pilot from the U.S.-led coalition to be captured. The video also showed footage of the aftermath of air strikes, with people trying to remove civilians from debris.

A man resembling Kasaesbeh is shown inside the cage with his clothes dampened, apparently with flammable liquid, and one of the masked fighters holds a torch, setting alight a line of fuel which leads into the cage.

The man is set ablaze and kneels to the ground.

Fighters then pour debris, including broken masonry, over the cage which a bulldozer then flattens, with the body still inside. The video showed a desert setting similar to previous videos of killings.

Jordan has vowed "punishment and revenge" for the killing, and its leader King Abdullah cut his trip to Washington D.C. short to address it. There was no further comment from the Jordanian government. The head of the Jordanian armed forces broke the news of the pilot's killing to his family, a member of the family told Reuters.

U.S. President Barack Obama said the video, if real, would redouble the determination of a U.S.-led alliance to degrade and destroy Islamic State. He said it would be another sign of the "viciousness and barbarity" of the militants.

"Whatever ideology they're operating off of, it's bankrupt," Obama told reporters.

Islamic State has released videos showing the beheadings of several Western hostages and said that it has killed two Japanese captives. The militants have come under increased military pressure from air strikes and a push by Kurdish and Iraqi troops to reverse their territorial gains in Iraq and Syria.
