Beirut - The parents of an Israeli teen executed by a boy in a video posted online by ISIS have denied the group’s claims that their son was a Mossad spy.
The video posted on Tuesday showed a boy fatally shooting Muhammad Musallam, an Israeli Arab accused by the group of having signed up as a jihadi to spy for Israel's intelligence service.
The video, published by the group's Furqan media outlet, showed Musallam, 19, sitting in a room wearing an orange jumpsuit, talking about how he had been recruited and trained by Mossad. He said his father and elder brother had encouraged him.
After that, it showed Musallam being escorted to a field and then being shot in the head by a boy, described by an older, French-speaking fighter as one of the "cubs of the caliphate".
Musallam's father, however, has denied his son was a spy, saying a month ago that his son had gone missing while on a tourist trip to Turkey.
Said Musallam and the youth's mother, Um Ahmad, wept at their home in East Jerusalem when they learned of his death. Clutching her son's photograph, Um Ahmad told reporters: "A spy of 19? How is that possible? Why would he have gone there if he were a spy?"

Said Musallam said his son had been trying to return home when he was captured. He accused the militants of forcing his son to say he was a spy before killing him just for show.
"Mohammad was told by them to say about himself that he works for the Israelis," Said Musallam said. "They took him as a victim, only to show the world, so the world would be afraid of them."
Reuters could not immediately verify the authenticity of the footage, which also appeared on Twitter feeds used by Islamic State supporters.
Israeli security officials said they were aware of the video but could not confirm that it was authentic.
The video, about 13 minutes long, showed Musallam on his knees when the boy armed with a pistol and wearing a military uniform fired one bullet into Musallam's forehead. The boy then fired three more shots into his body.
In the video, Musallam said he had joined Islamic State to report to the Israelis on weapons caches, bases and Palestinian recruits. Israel and his family denied that he was an Israeli spy.
An Israeli security official had said Musallam went to Syria to fight for Islamic State in October last year.
