ISIS
Many are now defecting from ISIS and some have been captured and are being held in a facility in Syria by rebel group/s. I believe there are around 300.
Some have been released, some will be put on trial if they have commited murders etc and will be dealt with under Syrian law...others wish to be repatriated back to where they came from. Whether they will be remains to be seen; many are from Europe.
I don't want any of them back here in Australia (if they are amongst this lot).
I agree with you Radish ... if they left here to fight against our soldiers on behalf of ISIS ... they should be stripped off their citizenship and never allowed to set a foot on the ground in Australia again.
