This is nothing new.
The bonds between straight males in many middle eastern countries or even as far as some countries in Eastern Europe manifest in very different ways than in our "simple minded" western minds.
Google "Djokovic boat party" and you may think Djokovic was holding a White Party for the gay boys. And Djokovic is as straight as it gets.

In countries where males and females don't mix up unless they are married (i.e. Muslim countries), it is not uncommon to see men hanging out very close to each other, touching legs, hugging (just like in your picture).
It is not viewed as gay it does not make them gay.
They are just very effusive with each other.
In my western mind I can think "closeted gays" but most likely I am wrong. It is just a different culture
