The Kurdish fighters, backed by US coalition air support, fended off the ISIS's attempted attack on SDF positions in Sa'din village, West of Tishrin Dam, and forced them back from the battlefield.
"Scores of terrorists were killed or wounded under the SDF heavy fire near the Tishreen Dam," Source told FNA on Tuesday afternoon.
The source said that the last night's attack of the ISIS militants was the third in less than seven days.
The Syrian Democratic Forces seized control of the Dam and almost a dozen villages in the nearby regions North of Aleppo province late December.
The Tishreen Dam is located on the Euphrates river at the border of Raqqa and Aleppo provinces.
The YPG Kurds have recently bonded with the Damascus government. The Syrian army sent several arms cargoes to the YPG troops in the Northeastern province of Hasaka and trained the first group of Kurdish volunteer forces in the provincial capital city of Hasaka last week.
The SDF that is comprised of mainly Kurdish fighters as well as a few hundred Syrian Arab dissident forces have received trainings from the US and have been provided with scanty US-coalition air support in their battles in Raqqa province in Northeastern Syria; but in Northern and Northwestern battlefronts, they have been operating alongside the YPG and received the Russian air backup in their Aleppo wars that started with the conquest of Tishrin Dam on the Euphrates early in February.
Assisted by the Syrian army - that has along with popular forces and Hezbollah conquered almost all militant-held regions in Eastern, Southern, Western and Northwestern Aleppo province - and Russian air support, the Kurdish forces fighting against the terrorists in North-Northeast Aleppo province have been making striking advances against the Al-Nusra, Ahrar al-Sham and ISIS terrorists in February.
Earlier this week, YPG and SDF fighters prevailed over the terrorists in the highly strategic city of Tal Rifat in Northern Aleppo and captured the city.
The YPG, who enjoyed the Russian air backup, prevailed the terrorists' positions from the Western direction and shook hand with the Kurdish units of the SDF who entered the town from the North, FNA reported.
