Two teenagers arrested in a Sydney counter-terror operation have been questioned overnight.

The 16-year-old boys were reportedly soon to launch an attack with bayonets-style knives before they were arrested near a Bankstown prayer hall on Wednesday afternoon.

Police say there is no ongoing threat following the arrests.

At least one of the teenagers has come to the attention of authorities previously for refusing to stand for the Australian national anthem while a student at East Hill Boys High School.

The ABC reports that when he was questioned over the incident he said he only stood for God and spoke about overseas military action by Australian troops.

Police wouldn't provide details of the operation but have said there is no on-going threat.
