The Australian government has not publicly confirmed whether or not an Australian killed overseas had ties to a registered terrorist organisation after saying it was looking into the alleged link.
The Department of Foreign Affairs and Trade initially confirmed the deaths of two Australian citizens - brothers Ibrahim and Ali Bazzi - in an Israeli air strike in southern Lebanon before Christmas.
It also said it was working to establish whether Ali Bazzi was a member of Hezbollah after the Shi'ite Muslim group - which Australia designates as a terrorist organisation - claimed him as one of its fighters.
