A Pentagon spokesperson said agreement with Turkey on safe zone in Northern Syria will be be implemented in stages.

Defense Department spokesman Commander Sean Robertson told AFP that the agreement between the United States and Turkey to establish a safe zone in northwest Syria will be implemented gradually, with some operations beginning soon.

The Pentagon spokesperson added: "We are currently reviewing options for the Joint Coordination Center with our Turkish military counterparts."

Robertson added: "The security mechanism will be implemented in stages. The United States is prepared to begin implementing some activities rapidly as we continue discussions with Turkey."

According to terms of the agreement between Ankara and Washington reached last week, authorities will use the coordination center, located in Turkey, to organize a safe zone in northern Syria.

The agreement aims at creating a buffer between the Turkish border and areas controlled by the Kurdish People’s Defense Units (YPG).
