@kennethamy,
That occurred to me, but I've no clue re hiking near Iran.
I have/had a pal in Los Angeles who emigrated back when, post shah. Mostly I listened to him, info gathering but also understanding him. From what I remember, he was a 'prince' in his area. His family owned major land, as I understand it.
Just because I liked this guy and his wife doesn't mean that I agreed with them then. I was well aware of nastybodies, as a friend used to say. And as many on earth can say about each other.
What I don't know is the background of these hikers. Maybe they are actual explorers. I know one of those.
I don't know the area, nor the reason anyone would hike there, casually or not, nor the trio's background.
