The military statement published late Saturday said the men were killed in clashes with Syrian Kurdish YPG and the Islamic State group. Eleven soldiers and four Syrian fighters were injured.
Turkey has been battling the YPG, which it deems a terror organization, to clear Afrin in northern Syria of the group.
According to the statement, 447 terrorists were neutralized since the beginning of the week-long operation codenamed Olive Branch. The figure cannot independently be verified because of access restrictions to the battleground.
In total, five Turkish soldiers have been killed since Jan. 20.
