The Australian federal police have issued warrants of arrest for two Aussie jihadists accused of fighting with the Islamic States. The two, Khaled Sharrouf and Mohamed Elomar, were also behind the posting of a viral photo in Twitter showing Elomar holding two decapitated heads.

Their threat to kill Australian soldiers and non-Muslims is being taken seriously by local authorities since the photo of the chopped heads is strong evidence to believe they are capable of really committing such heinous crimes. It prompted Attorney-General George Brandis to call the duo the biggest threat to national security.

He said the two have been promoting violent crimes and war crimes. While the Australian Federal Police said they want to arrest the pair upon their arrival in Australia, Sharrouf and Elomar told a friend that they have no plans of returning because they are living better lives now.

Brandis said the two probably left Australia in 2013 to fight in Syria and then moved to Iraq.

Elomar's wife, Fatima, is cnarged with supporting terrorists. Her lawyer, Zali Burrows, doubts if the Twitter images are real since she believes it has been Photoshopped.

The pair is just two of the more than 100 Australians believed to have left the country to join separatist groups in the Middle East. ASIO said the state is now one of the most deadly and active terrorist organisations in the world.
