Sky News host Sharri Markson has called for the Prime Minister to act after text messages allegedly revealed a teen terror cell, and in a separate incident children chanted for intifada at a proPalestinian protest.

A group of teenagers allegedly called themselves ‘soldiers of Allah’ and claimed they were ready to die and kill, and also allegedly spoke of getting hold of guns and looking for abandoned houses to use.

Further, at a proPalestinian protest at the University of Sydney on the weekend, children were filmed chanting antiIsrael slogans.

“Despite these shocking allegations – both about the alleged teen terror cell and the children chanting hate we've heard no outrage from the Prime Minister,” Ms Markson said.

“Imagine if children were chanting racist slogans that offended Indigenous Australians or the Islamic population? You know he wouldn't be silent then.

“His leadership on this is nonexistent. It's continued disappointment from a failure of a Prime Minister who has let us down, over and over and over again, in the past seven months.”
