ISIS released a new video on Tuesday which shows a child executing an East Jerusalem Arab who the radical terror group accused of being a Mossad spy.

Twitter accounts linked with ISIS published previews of the 13-minute clip showing the killing of Muhammed Said Ismail Musallam, a 19-year-old Arab Israeli.

The footage also presents several other individuals which the radical terror group claims are spies. “We are looking towards Jerusalem,” the groups says in the video.

Israeli officials told Reuters that they were aware of the videos existence and are in the process of authenticating the footage.

In the video, Musallam is seen kneeling before an armed jihadist and teenage boy in the notorious orange jumpsuit that have become key features of ISIS executions.

The boy, dressed in a military uniform, shoots Musallam several times with a pistol and chants “Allahu Akbar!”. The other man, speaking in French, goes on a tirade against Jews and threatened to attack Israel. He praised the recent terror attacks in Paris, in which four Jewish men were killed at a kosher supermarket.

“O Jews, indeed Allah has gifted us with killing your followers in your own stronghold in France. As for here in the Islamic State, here are the young lions of the Khilafah,” he stated. “They will kill the one sent by the foolish Mossad to spy on the secrets of the mujahidin and the Muslims.”

The ISIS terrorist vowed that the group “will liberate Jerusalem from you filth, by Allah’s permission.”

“Today we say to you the Islamic conquests have begun and the Jews have become frightened because the promise is near,” he stated, issuing a command for ISIS followers to attack suspected Mossad agents.

“We’ve revealed to you some of the names and pictures of the spies in Jerusalem and so make those who recruited them see their blood flow.”

Earlier in the video, Musallam is seen describing how he was recruited to the Mossad. An image of Musallam’s passport presents evidence of his Israeli citizenship.

In February, the ISIS magazine Dabiq featured an interview with Musallam describing how his Jewish neighbor, a police officer named Eli, recruited him to work for Israel.

The video ends with a list of names, occupations and home addresses of suspected Mossad spies.

A Shin Bet spokesman told AFP that Musallam left his home on October 24 “on his own initiative.”

Musallam’s family denied any allegations that their son was a spy for Israel’s most famous spy agency.

Musallam’s father, Said, told The Associated Press that his son left for Syria four months ago without telling the family. Soon after his disappearance, Musallam contacted one of his brother’s and told him he was going to fight with ISIS.

Later, Musallam contacted the family from Raqqa in northern Syria, a stronghold of the terror group, saying he wanted to return home.

“I saw him with a long beard and long hair and a Kalashnikov,” his father said. “He told me, ‘Look dad, I am fed up here, it is a country of war, and I want to come back.’”

A month ago, the family was told by an anonymous phone call that Musallam was captured by ISIS when he tried to flee. He was caught at a Turkish checkpoint and put in ISIS jail.

“They did not want to let him leave because if he comes back, he might be caught by the Israelis and tell them what he had seen. So they wanted to get rid of him,” the father said. “I know my son. I raised him well. I am sure he’s not working for the Mossad.”

A growing number of Israelis are believed to be leaving Israel to join up with ISIS. Intelligence reports estimate that the radical terror group as attracted 20,000 foreign fighters to its ranks.
