According to sources, YPG is getting indirect help from Assad’s government.
Damascus shows no sign of doing so, but it is providing indirect help by allowing YPG fighters, civilians and politicians to reach Afrin through territory it holds, representatives of both sides told Reuters.
Each side has allowed the other to maintain footholds in its territory. In YPG-held Qamishli, Assad still controls the airport. In the Sheikh Maqsoud district of Assad-held Aleppo, YPG security forces patrol the streets.
