A Nordavia Boeing 737-500, flight 5N-9225 from Arkhangelsk (Russia) to Antalya (Turkey) with 133 passengers, was enroute about 1.5 hours into the flight when the crew decided to turn around and return to Arkhangelsk due to strange noises from a forward main door. The aircraft landed safely in Arkhangelsk about 3 hours after departure.
The airline confirmed the return to investigate the strange noises from the door.
