According to witnesses, the plane crashed in a ball of flames near Kavala before exploding on impact in corn fields about midnight local time. The pilot had previously reported engine issues and sought an emergency landing.

Drone footage from the incident revealed smoking Antonov An-12 airplane debris spread over fields.
