ASSOCIATED PRESS-- The military says the soldier was killed late Monday by a mortar-and-rocket attack. Five Turkish soldiers and a civilian military contractor were wounded.
Turkey began deploying forces in an observer role to the rebel held Idlib in northwestern Syria in October.
That deployment is separate from a Turkish military offensive that Ankara launched last month to rout U.S.-backed Syrian Kurdish fighters from the northern enclave of Afrin.
Syrian government forces are on the offensive in Idlib, where militants shot down a Russian Su-25 over the weekend.
