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.
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 fake 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 had been attempting to secure Lt Kasasbeh's release as part of a prisoner swap, offering to free 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.
