Seems like you don't know what you're talking about. I just leave this here:
The Syrian Observatory for Human Rights monitor confirmed regime forces had taken control of large parts of Al-Hader, which had been largely controlled by Al-Qaeda affiliate Al-Nusra Front and other allied Islamist groups
"The town is the biggest headquarters for rebel forces in southern Aleppo, and capturing it would bring the army closer to the key Aleppo-Damascus highway," Observatory chief Rami Abdel Rahman said.
The Britain-based monitoring group said both Syrian and Russian warplanes were carrying out strikes in the area, and the regime forces and their allies have advanced west to the town of Al-Eis.
"Today's advance is the most important strategic advance for Syrian regime forces since the Russians began their air strikes," Abdel Rahman said.
"The area is key because it is elevated and if they capture it they will have line of fire sight over the Aleppo-Damascus highway."
