Helmets belonging to the two missing pilots of the downed Turkish jet were found alongside parts of the plane wreckage, Transportation Minister Binali Yıldırım said, according to daily Hürriyet.
The search for the missing pilots continues, Yıldırım said.
Two pairs of boots, also believed to belong to the missing pilots were found several days before, Prime Minister Recep Tayyip Erdoğan
had said during a meeting with opposition leaders.
There were no signs of parachutes near the wreckage and the pilots may not have used their ejection seats, according to information provided by the prime minister.
Turkish naval and air forces have been attempting to locate Capt. Gökhan Ertan and Lt. Hüseyin Aksoy since their jet was hit by Syrian forces in international waters on June 22.
