A seventeen-year-old boy who ran away from his family to fight alongside Islamic State terrorists in Iraq and Syria has featured in another chilling propaganda video.

Bankstown teenager Abdullah Elmir is seen holding an AK-47 rifle in the new six-minute clip, which shows jihadists eating and praying on the banks of the River Tigris in Mosul in Iraq.

Entitled ‘An evening on the banks of the Tigris River in the Province of Nineveh in the Islamic State’, the propaganda video includes threats from various speakers who say they will “strike the necks of the infidel and Arab countries”.

The teenager went missing in June after telling his family he was going on a fishing trip, and was featured in an Islamic State video last week telling world leaders the fighters would “stop at nothing”.

Immigration Minister Scott Morrison said Elmir had “fallen victim to a barbaric and brutal portrayal of his own religion”.
