"The joint operation center has started working at full capacity. The command of center is by one U.S. general and one Turkish general," state-run Anadolu news agency quoted Akar as saying.
The first joint helicopter flight was due to take place on Saturday after Turkish drones carried out surveillance work in the safe zone area last week, the Turkish defence minister said.
The announcement on the formation of a joint operations centre was announced by Ankara and Washington earlier this month, following threats from Turkish President Recep Tayyip Erdoğan on an imminent military operation against the groups south of Turkey’s border.
Turkey and the United States have been at odds over plans for northeastern Syria, where the YPG formed the main part of a U.S.-backed force fighting DAESH.
Around 90 U.S. soldiers arrived in Turkey this week in hopes of an agreement on a safe zone that will be acceptable both to Turkey and the Syrian Kurdish autonomous administrations governing the north and east of Syria.
