Incidentally, the previous footages of execution of their hostages had beheadings, but this one was slow and painful. And the militants attribute it to the role Jordan has played in 2005 bombing attack in the country's capital.
Meanwhile, furious at the new development, the Jordanian military on Tuesday said,"The blood of our hero martyr Muath al-Kaseasbeh will not go for nothing.And the revenge will be equal to what happened to Jordan."
Unconfirmed reports believe that the pilot was executed on Jan 3, before the militants struck negotiation with the Jordanian authorities. The former had initially demanded the release of a would-be female bomber Sajida al-Rishawi for the Japanese journalist and the Jordanian pilot.
However, negotiations broke down despite the fact that Jordan was willing to give away the militant when the IS said that they would release only the Japanese journalist if their demands were met. They set a deadline for Jan 28. Once the deadline passed, the video was released.
In the final moments of the video, the pilot is shown caged and his jumpsuit soaked in what appears to be gasoline. A hooded Islamic State militant lights the torch. The pilot is engulfed in flames. He collapses on his knees and then falls back.
At a White House, President Barack Obama said he was aware of the footage. "It's just one more indication of the viciousness and barbarity of this organization," he said. "And I think it will redouble the vigilance and determination on the part of the global coalition to make sure that they are degraded and ultimately defeated."
