Thirteen Australians in Islamic State leaks, says counter-terrorism analysis

Thirteen Australian residents appeared in a massive cache of Islamic State registration documents leaked to news organisations last month, according to a US army college analysis.

The figure, published by the Combating Terrorism Centre at West Point, is 11 more Australians than has been previously reported.

Thousands of apparent Isis registration documents were published by a Syrian opposition site in January and then more leaked in March to the German daily Süddeutsche Zeitung.
