Joseph Dunford spoke with Gen. Yasar Guler Wednesday, according to Col. Patrick S. Ryder, a spokesman for the Department of Defense.

The two leaders discussed the current security situation in Syria, and the U.S. emphasized it enjoys a strong military-to-military relationship with Turkey as "key members of the NATO alliance."

U.S. President Donald Trump announced in December that Washington would be withdrawing all troops from Syria, however the administration later stated they will be keeping a small force in the region to maintain stability.

"They also addressed the completion of the Manbij roadmap and the importance of continued U.S.-Turkish cooperation on counterterrorism efforts to ensure the lasting defeat of IS," Ryder said in a statement.

In line with the Manbij roadmap, Turkey and the U.S. are conducting joint investigations for the restructuring of civil and military councils in northern Syrian town of Manbij.
