Anti-terror police have raided two homes in Melbourne's outer north in an operation thought to have targeted an Australian man who appeared in an Islamic State propaganda video.
Australian Federal Police have confirmed the Victorian Joint Counter Terrorism Team executed warrants at homes in Meadow Heights and Craigieburn on Thursday morning.
The team comprises AFP officers, Victorian police, ASIO agents and other agencies.
"There is no immediate danger to the community as a result of this police activity," the AFP said in a brief statement to AAP late on Thursday.
"As this matter relates to an ongoing investigation, no further comment can be provided at this time."
The AFP has not stated whose homes were raided.
The ABC reports that the homes are occupied by the ex-wives of Mohomed Unais Mohomed Ameen, 41, who appeared in an IS video along with Australian doctor Taeq Kamleh in what was presented as an IS-operated hospital in Syria.
It says Ameen travelled to Syria in May 2014 and is acting as a physiotherapist.
Ameen may be linked to the Anzac Day terror plot and a bookshop in Springvale that itself is linked to Australians who have travelled to the Middle East to join IS, the ABC said.
