According to a General Staff statement, Akar carried out his visit with commanders of the Turkish Land and Air Forces.
The statement added that Akar was briefed on recent developments in Operation Euphrates Shield, across the border in northern Syria.
Operation Euphrates Shield began in late August 2016, to tighten border security, eliminate terror threats along the Turkish border, and support opposition forces in Syria. In the operation, the Free Syrian Army (FSA) is backed by Turkish forces.
FSA fighters have been concentrating on liberating the Daesh-held town of Al-Bab, 40 kilometers (25 miles) northeast of Aleppo.
