It means take any news from them with a very large grain of salt. I’ve posted articles from them, but IIRC, I add “Iranian state television” after their name.
I think one needs to down the whole salt shaker with this article. It’s the second time Iranian Press (gov’t) has announced the King as being dead. And, there are no other sources reporting any of this - all Iranian sources (save for one Serbian media outlet), and they are all based on the same single article.
Would the Iranian Press ever report the truth? Only when it suits the agendas of the Mullahs...
