An Australian teenage runaway, dubbed the Ginger Jihadist by the media, has been featured in a second Islamic State propaganda video.

Australian media reported the latest YouTube video of 17-year-old Abdullah Elmir dressed in Arabic garb and clutching an assault rifle on Tuesday as the Senate prepared to debate legislation that would simplify prosecuting Australian extremists who fight in the Middle East.

Abdullah vanished from his Sydney home in June, telling his family he was going fishing.

He appeared in his first Islamic State video last week warning that the movement won't stop fighting until the extremists' notorious black flag is flying above every nation.

News Corp. Australia newspapers reported In the latest video was shot on a bank of the Tigris River in Mosul in Iraq.
