Second Northern Syria Buffer Zone
The Second Northern Syria Buffer Zone, part of the Sochi Agreement (Turkish: Soçi Mutabakatı, Russian: Сочинское соглашение), was a buffer zone in northern Syria between the Turkish Armed Forces (TAF) and the Syrian Democratic Forces (SDF). It was set up following a memorandum of understanding in the Russian city of Sochi on 22 October 2019 by the Russian and Turkish presidents during the 2019 Turkish offensive into north-eastern Syria.
