A new graphic video has been released by Isis showing a man digging his own grave before he is shot by the jihadist fighters.

The highly-stylised video, which was released on 10 June, shows the bearded man wearing a Guantanamo Bay-style orange jumpsuit digging what looks like a grave in the sand. It then cuts to the moment that appears to be his arrest, where he is seen wearing a lilac dress shirt as he frantically speaks Arabic on the phone.

The video then pans back to the man near the dug out grave as he mumbles to himself and an Isis fighter stands behind him. According to the Daily Mail, the fighter is then seen taking out a small handgun and shooting the prisoner in the back of the head.

In the final moments of the video, the murdered victim is pushed into the grave and is covered by his executioner.

The Isis-affiliated terror cell in Egypt accused their victim of being a Mossad spy who operated in Sinai and reported back to the Israeli government of Isis's activities. The gruesome footage was shot in Sinai province.

The Daily Mail reported that the Sinai cell of Isis is one of many operating outside of Isis's self-proclaimed caliphate in Syria and Iraq. The Sinai branch, which reportedly has 2,000 members, are cited as being responsible for a series of car bomb attacks in the country this year.

The terror cell, Ansar Bait al-Maqdis, reportedly defected from al-Qaeda in November 2014 and instead pledged allegiance to Isis leader Abu Bakr al-Baghdadi. The terrorist group also operates in Gaza Strip, according to the Daily Mail.

According to NBC News, the terror cell is likely responsible for the recent attack to Karnak Temple in Luxor. The popular tourist attraction was the site of a foiled terrorist attack, which ended with the death of two assailants and injuring a third person.
