The ongoing tensions between the US-backed Kurdish forces and pro-government militias in the city of Hasakah (click here for more info) has started to affect the situation in Aleppo city.
On August 21, the Kurdish People’s Protection Units (YPG) forces that are in control of the Sheikh Maqsoud neighborhood of Aleppo city reportedly shelled the Castello Highway, the only government supply line to areas of western Aleppo because of the ongoing clashes between the Syrian army and the joint forces of various militant groups in southwestern Aleppo.
Radio Hara, a pro-militant media outlet located in Aleppo, even reported that the YPG has closed the Castello Highway for government supply convoys. However, this can not be confirmed.
Technically, it will be almost impossible for the YPG to take control over the Castello Highway. However, the group will likely be able to shell some parts of this crucial supply line on a constant basis. This move will worsen the situation in the government-controlled areas of western Aleppo, but it also puts the YPG in very complicated situation because the US-backed Kurds have no allies among militants from the Jaish al-Fatah operation room (includes Al Nura & co) that clash with the Syrian government forces for the control of the city.
