A man accused of being a member of the self-proclaimed Islamic State (IS) group has been arrested by counter-terrorism agents over allegations that he instructed people on how to plan and conduct mass-casualty attacks from his base in Australia.

The Melbourne man, whom the Australian Federal Police (AFP) alleges was a propagandist for the extremist group, is accused of sending about 10,000 documents, messages, images, videos and audio files relating to executions and torture.

The 65-year-old retiree allegedly pledged allegiance to the IS group between 2018 and 2020.
