Islamic State jihadists returning from Iraq sparks rejuvenated terror threat from Indonesia, experts warn

One of the leading experts on south-east Asian extremist groups is warning that jihadists returning from Iraq and Syria could rejuvenate terrorism in Indonesia.

Speaking at the Lowy Institute in Sydney, Jemaah Islamiyah (JI) expert, Sidney Jones said the expertise fighters gain with groups such as Islamic State (IS) could eventually be a threat to westerners.

In recent years Indonesian authorities successfully cracked down on jihadist groups and the extremist movement had become weakened and fragmented.

But Ms Jones said IS could prove to be the catalyst that re-awakens jihadi violence with Australians knowing all too well the danger radical Indonesian jihadist movements pose.
