Here's The Guardian:
Ok, so an Australian was held prisoner by Israel without charge or trial and eventually seems to have killed himself though of course he could have been killed. Let's just remind ourselves that this guy wasn't the only one to be held by Israel without charge or trial but that's not the point here. This guy was a father of two from Australia and Australia is an ally of Israel. Did the Australian government know anything about him?
So some officials knew some stuff but not the foreign minister. So what does he do now he knows?
It could because I'm in the UK that ABC's own reports didn't come up prominently in the google search but there's a lot on this case including information about the family on the ABC News website.
But aside from all the questions about who the guy was and what was supposed to have done it does seem clear that he was Australian and Jewish and he died in an Israeli jail. So what is Australia going to do about it? My guess is they'll quietly drop it.
