Middle East or not in Europe (not sure about the east part) this is highly inappropriate. Even in the South were they have much smaller personal spaces (which annoys us, cold Northerners) there's a no hugging policy.
Though I must say when I worked in Italy the work environment was a bit different- I did endure some talks about my personal life (as was the common practice and I dealt with it by creating a fiancé at home waiting for me to get married ), literal patting on backs, hands resting on shoulders when in convo... from my superiors (male and female alike) but NEVER hugging. It was a bit uncomfortable for me (esp in the beginning) but I never felt like I was singled out. So common it was that I probably would have felt weird, had they not treated me that way.

If you think contacting your T would help you speak up, please do so. The earlier you'll say stg the better. : one safe hug if wanted :
