U snimku dugačkom 13 minuta, koji je objavljen sinoć na Twitteru, vidi se kako muškarac sjedi i mirno priznaje da ga je regrutirao izraelski Mossad, a navodi čak i koliko je za to bio plaćen, objavio je Fox News. 

Obitelj Muhameda Musallia je kasnije identificirala muškarca na snimci kao njihovog sina.

Musalli u videu priznaje da ga je za Mossad vrbovao jedan susjed Židov, a izraelska obavještajna agencija je od njega tražila da se infiltrira u Islamsku državu i osigurava im informacije o mjestu oružja i baza, kao i imena Palestinaca koji se bore na strani džihadista.

Pri kraju videozapisa, jedan muškarac je na francuskom zaprijetio Židovima u Francuskoj, nakon čega je dječak stao ispred Musallia, koji je klečao na podu, i upucao ga iz pištolja u čelo.

Palestinac se zatim srušio na pod, da bi ga dječak, vičući “Alahu Akbar”, upucao još četiri puta.

To nije prvi put da džihadisti Islamske države koriste maloljetnike za izvršenje pogubljenja, pa je tako u siječnju objavljen video snimak na kojem se vidi kako jedan kazahstanski dječak ubija dvojicu ruskih taoca.

“Islamska država od ove godine forsira svoj ‘program obuke pionira’. Korištenje djece ubojica je značajno jer IS time pokazuje da njihov kalifat ‘raste’ i da oni sada podižu novu generaciju ratnika”, ocijenio je urednik “Konzorcija za istraživanje i analizu terorizma” s Floride, Veryan Khan.

The child executioner: New horrific ISIS video shows boy aged about 10 shooting dead ‘Israeli spy’ at point blank range – but is slickly-produced hi-def film all it seems?

• New clip purports to show execution of Muhammad Said Ismail Musallam
• The 19-year-old Israeli-Arab was captured by militants in Syria last year
• His family said he travelled to the region to join ranks of the terror group 
• But in their propaganda, ISIS claim he has admitted to being an Israeli spy 
• In slickly-edited video, Mr Musallam describes Jerusalem training camp
• He is later seen kneeling in field in front of two uniformed ISIS militants
• One of them, a young boy, appears to shoot the hostage at close range
• But careful editing means it is impossible to tell whether he pulled trigger 
• The child then raises the gun, shouting ‘Allahu Akbar!’ in celebration

Islamic State militants have released a sickening new video that purports to show a boy shooting dead a 19-year-old Israeli-Arab who was taken hostage by the terror group.

The film shows a man identified as Muhammad Said Ismail Musallam describing how he was sent by Israeli intelligence to infiltrate ISIS in Syria, where the group claim he was captured last year.

Wearing an orange jumpsuit, the hostage is later kneeling at the feet of two uniformed militants, one of whom appears to be no older than 10, before being shot in the forehead at point-blank range. 

But while ISIS claim the child – described in the video as one of the ‘cubs of the caliphate’ – was the shooter, careful editing means it is impossible to tell whether he pulled the trigger.

Earlier today, Twitter accounts linked to the terror group shared preview clips of the video, which has not been independently verified. 

Islamic State claimed Mr Musallam had posed as a foreign fighter when he joined their ranks last year but later confessed to being an agent for Mossad, the Israeli intelligence agency. 

The accusation has been denied by an Israeli security official and by his parents – who claimed he had travelled to the region to fight alongside the jihadists. 

The video, published today by the group’s Furqan media outlet, is the latest in a series of propaganda videos that purportedly show the execution of ISIS hostages, including three Britons.

It also lists the names of 13 other men – including Mr Musallam’s elder brother and father – who the group claims are working for Mossad.

Sickening: Mr Musallam appears to be shot three more times as he lies dying on the ground

Featuring graphics, re-enactments and a number of camera angles, the film includes a number of camera effects and cut-away shots that give it a ‘computer game’ look.

It starts with an animated ‘fact file’ of Mr Musallam – complete with what appears to be a picture of the inside of his passport – that claims to show his home address and profession.

The video, apparently filmed on a number of cameras, shows Mr Musallam wearing an orange jumpsuit similar to those worn by hostages featured in previous ISIS videos. 

Speaking in Arabic, the young man remains calm and controlled as he tells of how he was recruited by a neighbour who worked for the Israeli police. The entire video is subtitled in English. 

He says that his father and brother both encouraged him to take up the position, pointing out there would be opportunity to progress in the organisation.

Slick: In the first part of the video, Mr Musallam is seen describing how he was recruited by Israeli intelligence

He adds: ‘I knew at that point they themselves were working as spies’.

Mr Musallam goes on to describe how he was trained to use weapons and withstand interrogation techniques at a camp in Jerusalem before being sent to Syria on a mission.

He explains he was told to infiltrate the Islamic State and send information on weapon stores, training bases and Palestinian members of the group back to Israel. 

In what appears to be a rehearsed speech, Mr Musallam talks about how he entered Turkey before being smuggled across the border to Islamic State-occupied Syria.

He shares of how he was caught and interrogated by jihadists after they became suspicious when he left a guest house where he was staying to make a phone call to his father.
