Witnesses said the aircraft had come down in a ball of flames near the city of Kavala before exploding on impact in corn fields around midnight local time. Earlier the pilot had reported engine trouble and had requested an emergency landing.
Drone images from the scene showed smouldering debris from the Antonov An-12 aircraft strewn across fields.
Ukrainian-based airline Meridian, which operated the aircraft, confirmed that all eight crew members had died in the crash. Ukraine's foreign ministry said they were all Ukrainian citizens.
