Police in Australia say two men arrested with a machete, hunting knife and home-made Islamic State flag in a raid on Tuesday were going to carry out a terror plot later that day.
Australian broadcaster ABC says police believe one of the men had made a video of himself in front of the banner just 20 minutes before police stormed into his suburban Sydney home.

New South Wales deputy police commissioner Catherine Burn said: "We believe that the men were potentially going to harm somebody, maybe even kill somebody, and potentially using one of the items that we identified and recovered yesterday, potentially a knife."
"When we did the search of the premises, a number of items were located, including a machete, a hunting knife, a home-made flag representing the proscribed terrorist organisation IS, and also a video which depicted a man talking about carrying out an attack.
"I would like to however reassure the community that we are of the view that there is no further imminent attack relating to these two men."
Police say the two were planning to target either beat police officers or a police station, Channel 9 News reports.
According to Sky News Australia, detectives are trying to establish whether the men had been in contact with IS, the Sunni fighters who have set up their own extremist 'state' in Syria and Iraq.
Burn said the "imminent attack" was "consistent with the messaging coming out of IS".
