ISIS militants have posted a new video appearing to show the killing of an Israeli Arab man whom they accused of being a spy.

In the video, a 10-year-old boy from ISIS Young Lions is seen apparently shooting a man the militants identified as Said Ismail Musallam.

ISIS said Said Ismail Musallam, 19, had posed as a foreign fighter when he joined the militants in Syria.

It said he later confessed to being a spy for Israel’s Mossad – a charge denied by Israel and by his family.

They say Said Ismail Musallam went missing after travelling as a tourist to Turkey in 2014.

A few months later an online magazine linked to ISIS carried a long interview in his name in which he confessed he had been sent by Israel to infiltrate the organization.

The video purportedly showing Said Ismail Musallam’s death has not been independently verified.

It is the latest in a series of ISIS propaganda videos appearing to show the killing of hostages.

Last month ISIS militants in Libya released a video showing them beheading 21 Coptic Christians.
