Australian security agencies are on increased alert after two Australians were killed in an Israeli air strike in south Lebanon.
Hezbollah has claimed that one of the Australian citizens killed was a fighter for the terrorist group.
National security experts warn there is a heightened risk of Australians joining overseas terrorist organisations, particularly those planning attacks against Israel.
Acting Home Affairs Minister Andrew Giles said the government is working closely with agencies to prevent radicalisation and attacks within Australia.
The AFP is warning Australians who travel overseas to fight with non-government armed groups, such as Hezbollah, may be committing a criminal offence.
