Arresting and imprisoning people within their own borders without formal charges is also a Saudi Arabian practice. And it's a far cry from murdering someone in one of their embassies in a foreign country.

Now, maybe Iran actually does do that? The difference is that they have to at least do a competent job covering it up because unlike KSA they don't act with complete immunity to any consequences or repercussions for their actions.
