Two Australian members of ISIS were targeted by US-led airstrikes in Iraq.
Neil Prakash, a top recruiter for the terrorist group and alleged to have plans to launch attacks in Australia, was killed a week ago in Mosul during a meeting it has been reported.
The second Australian, Shadi Jabar, was reportedly killed in the Syrian city of Al-Bab.
“This should serve as a reminder to any Australians who seek to go to or are in the conflict zone that they are targets and they should expect to be killed as we continue our campaign to eliminate this terrorist group,” Australian Prime Minister Malcolm Turnbull said on Thursday.
“We are unrelenting in the war against Daesh (ISIS) right around the world and Australians who think they can go to Syria and Iraq and fight with Daesh have to recognise that they will be targeted,” Mr Turnbull said.
Attorney-General George Brandis said on Thursday that he could not detail how Australia helped identify and locate Prakash.
“Sometimes it takes quite a while to isolate and locate a target so that they are able to be hit at a time when there will not be collateral damage,” he said.
“I can’t go into the details or the methodologies of any particular case but Australia did co-operate with the United States in relation to the identification and location of Prakash.”
Senator Brandis described Prakash as “the principal Australian reaching back from the Middle East … to the terrorist networks in both Melbourne and Sydney”.
The Australian Security Intelligence Organisation estimates that around 110 Australians have joined ISIS in Syria.
