A new video has surfaced that reportedly shows the youngest son of Australian ISIS terrorist Khaled Sharrouf wearing a suicide vest and threatening to murder Australians.

Cabinet minister Matt Canavan has described the video and treatment of the boy as a form of child abuse.

“It is reprehensible it, has to be condemned and I trust the proper authorities will look into this matter,” he told Sky News on Sunday.

It’s not the first time Sharrouf has used his children in this way.

He first gained infamy in 2014 after another of his sons was pictured holding the severed head of slain Syrian soldier.

The Sunday Telegraph said on Sunday the video was shot recently and shows the eight-year-old being asked questions including, “How do you kill an Australian?”, by his father who was off-camera.

A police spokesman said the NSW Joint Counter Terrorist Team was investigating the video, but said “there is no specific threat.”

Australia’s terrorism threat level remains at ‘probable’, he said.”

Senator Canavan said he felt for the boy.

“It’s not his fault that his father is an evil megalomaniac seeking to abuse his own children.”

In 2015, there were unconfirmed reports Sharrouf had died in a drone strike in Mosul. However he continues to be the subject of an active arrest warrant.

He went to fight with Islamic State in Syria in 2013, a year after being released from prison for his role in a terrorism plot.

His wife, Karen Nettleton, died in 2015, leaving the children in the Middle East.

Her mother Tara has tried unsuccessfully to bring the children back to Australia.
