The Islamic State (Isis) held a public viewing in their de facto capital of Raqqa, Syria, of the video showing the burning to death of captured Jordanian pilot Moaz al-Kasasbeh, according to reports.

The SITE Intelligence Group, which monitors and analyses news and videos from jihadist groups, reported that IS screened the barbaric execution in the Syrian city and recorded the cheerful reaction of men and a boy in the watching crowd.

In the latest video, titled "Muslims' Joy at Burning of Jordanian Pilot", IS supporters are seen shouting the Takbir - Allahu Akbar - as the execution footage in a background screen shows the pilot burning to death in his cage.

Members of the Raqqa crowd are briefly interviewed about the gruesome execution, in a documentary-style, while the video plays in background. Among them a smiling child, not older than eight-years-old, who is seen praising the murder.

The original murder clip, published online by IS militants, showed Kasasbeh standing in a cage engulfed in flames and being burned alive. The death of the 26-year-old Jordanian pilot, who was captured by the Islamist militants in December 2014 as his F-16 crashed near Raqqa, was confirmed by Jordanian authorities.

The SITE report seems to confirm earlier rumours that IS used large viewing screens and movie projectors across Raqqa to play the gruesome clip of the pilot's killing.

The Twitter account of Raqqa_SI, a small activist collective which secretly documents the shocking violence and oppression inflicted by IS on their claimed home city, revealed that the jihadists wanted the public to watch the burning of Jordanian pilot again and again:

Jordan executed female suicide bomber Sajida al-Rishawi following the release of the gruesome video.

Al-Rishawi, 44, was imprisoned in Jordan after attempting to detonate an explosives belt as part of the devastating 2005 hotel bombings in the capital city of Amman.

Jordan had earlier vowed to give an "earth-shattering" response to the IS militants after it emerged that they had executed the pilot.
