A source on the ground told Sputnik that the Syrian army continued to strengthen its positions in the northwest of the district of Manbij.
On Friday, the Syrian army announced it had entered Manbij after receiving an appeal from the Kurdish People's Protection Units' YPG to take control over the city amid Turkey's plans to start a military operation there. On Saturday, the Kremlin confirmed that Damascus had indeed regained control over the territory.
