The US and Turkey launched a second round of joint patrols in north-eastern Syria on Tuesday (September 24th) as part of plans to create a "safe" buffer zone, the Turkish defence ministry said.
Four Turkish armoured vehicles crossed the border to join US forces in Syria, state news agency Anadolu said, for patrols around the town of Tal Abyad, AFP reported.
The ministry said drones were also deployed.
Washington and Ankara reached a deal last month to establish a safe zone between the Turkish border and Syrian areas east of the Euphrates river controlled by the Syrian Kurdish People's Protection Units (YPG).
The first joint patrols were conducted on September 8th.
