in the area, the last remaining opposition stronghold for years. Hezbollah was “the main force” in the government’s control of Aleppo, said Rami Abdurrahman, head of the Observatory. In a phone call with his Syrian counterpart, Iranian Foreign Minister Abbas Araghchi described the insurgent attacks in Syria “as a plot orchestrated by the U.S. and the Zionist regime following the regime’s defeat in Lebanon and Palestine.” Insurgents posted videos online showing they were using drones, a new weapon for them. It was not clear to what extent the drones were used on the battleground. Insurgents attacked a military airbase southeast of Aleppo with drones early Friday, destroying a helicopter, the Anadolu Agency reported. The opposition groups also seized heavy weapons and military vehicles belonging to the government forces, the agency said.
