The Al-Nusra Front and their allies tried to take control of Sheikh Maqsoud area, but they were forced to retreat by the YPG fighters.
The Takfiri terrorists sustained heavy casualties and losses in fierce clashes with the Kurdish forces.
In a relevant development on Thursday, the Syrian Democratic Forces (SDF) and the YPG were preparing to launch a large-scale operation to liberate a strategically important city in Aleppo province from ISIL's control.
According to sources, the operation was aimed at liberating the city of Manbij, about 35 km from the Turkish border, which serves as a major stronghold for the ISIL in Northwestern Syria, and is an intersection of several major highways, including M4.
The operation was expected to begin in March, but was delayed due to the Turkish opposition, sources explained.
Liberation of the villages around Al-Bab is expected to eventually allow for the creation of a corridor between the Syrian Kurdish cantons of Kobani and Afrin, presently separated by the ISIL-controlled territory; FNA reported.
