Jordan pilot hostage Moaz al-Kasasbeh 'burned alive'

The BBC's Paul Adams: "The mood here in Amman tonight is furious"
Jordan has confirmed the death of pilot Moaz al-Kasasbeh after a video published online by Islamic State (IS) claimed to show him being burned alive.
The video shows a man standing in a cage engulfed in flames. Officials are working to confirm its authenticity.
Jordan's King Abdullah hailed Lt Kasasbeh as a hero, saying Jordan must "stand united" in the face of hardship.
The pilot was captured when his plane came down near Raqqa, Syria, during a mission against IS in December.
The video posted on Tuesday was distributed via a Twitter account known as a source for IS propaganda.
The highly produced 22-minute film includes a sequence showing the Jordanian pilot walking at gunpoint amongst rubble apparently caused by coalition air strikes that targeted jihadists.
BBC security correspondent Frank Gardner says that in a world already shocked by the calculated cruelty of Islamic State's actions, the horrific video is aimed primarily at Arab populations in Jordan and the Gulf states.
Jordanian state TV reports that Lt Kasasbeh, 26, was killed a month ago. Jordan had tried to secure his release since then.
The country has vowed "punishment and revenge" for his death, and the king described IS as a "deviant criminal group".

Jordan, which has joined the US-led coalition against IS, had been attempting to secure Lt Kasasbeh's release as part of a prisoner swap, offering to free Iraqi militant Sajida al-Rishawi in exchange.
She is a failed suicide bomber now on death row in Jordan for her role in attacks in the capital, Amman, that killed 60 people in 2005.
IS had sought Rishawi's release as part of a deal to free captive Japanese journalist Kenji Goto. A video that appeared to show Goto's dead body appeared three days ago.

Jordanians greeted the news with horror. Many have seen the gruesome video, barely edited, played over and over on television.
Hundreds gathered in the streets after dark, demanding revenge against Lt Kasasbeh's killers. Some also wanted to know why Jordan was involved in this fight at all.
The pilot's father was among supporters when the news came through. He and other family members have left the capital to mourn at home.
King Abdullah said Lt Kasasbeh had died defending his beliefs and homeland. The defence ministry said the pilot's blood would not have been shed in vain. It is promising a fitting punishment.
For many Jordanians, this has to begin with the quick execution of Sajida al-Rishawi, the failed al-Qaeda suicide bomber, jailed 10 years ago for her part in a spate of bombings against hotels here.
A spokesman for the Jordanian armed forces, Mamdouh al-Ameri, said Lt Kasasbeh had "fallen as a martyr".
"His blood will not be shed in vain," he said. "Our punishment and revenge will be as huge as the loss of the Jordanians."
Jordanian officials were quoted as saying Rishawi would be executed imminently, along with three other convicted militants.

One thing is clear from this video - Islamic State never had any intention of releasing the young Jordanian pilot. According to Jordanian state media he was killed on 3 January, well before the supposed prisoner exchange talks moved into high gear.
The cynical manipulation of this episode by IS shows the importance it affords to information warfare - here an attempt to create problems for the Jordanian authorities and to weaken the Arab-Western coalition, at a time when it appears to be struggling to make dramatic headway against IS on the ground.
This is the problem for the coalition. Its air campaign is in many ways a stop-gap intended to halt the progress of IS, but requiring effective troops on the ground to significantly turn back its advance.
Jordan's King Abdullah is cutting short a visit to the US after news of Lt Kasasbeh's death, but he met President Barack Obama on Tuesday evening before flying home.
Mr Obama earlier said in a statement that if the video was real, it would be "one more indication of the viciousness and barbarity" of IS.
"I think it will redouble the vigilance and determination on the part of the global coalition to make sure they are degraded and ultimately defeated," he added.
The Jordanian king has already met US Vice-President Joe Biden who "reinforced America's ironclad support" for Jordan, the White House said.
