The aircraft’s five crew members were Russian and three Turkish nationals were also on board, the Russian Defense Ministry said in a statement on Saturday, according to state news agency TASS.
The Be-200 amphibious aircraft crashed as it was due to land near the southern city of Adana.
A commission from the Russian Defense Ministry has been sent to the crash site to establish the causes of the accident.
Images of the crash site released by DHA Turkish News Agency showed charred wreckage littered across mountainous terrain with only the aircraft’s tail apparently still intact.
The governor of the southern Kahramanmaras district in Turkey, Ömer Faruk Coşkun, told Turkish state news agency Anadolu: “This is still very new right now. We sent a large number of teams to the area where the plane crashed.”
Turkey is one of many countries around the Mediterranean Sea that has battled devastating wildfires as the region experiences a relentless heat wave. At least eight people have been killed in the fires in Turkey, while more than 30 have died in floods in the northern provinces near the Black Sea in recent days.
Scientists say the climate crisis is making heat waves, fires and flooding more regular and intense.
