“Iran will continue to back Syria in its battle against terrorism,” Zarif said during a Wednesday phone conversation with Syria’s Foreign Minister Walid al-Muallem.
The Iranian foreign minister also congratulated Muallem for the Syrian army’s breaking of years-long Daesh siege of the eastern city of Dayr al-Zawr.
He also highlighted the significance of boosting the Tehran-Damascus relations in all fields.
For his part, Muallem voiced his country’s gratitude for Iran’s continued support, and vowed that the Syrian army would not rest until the country is liberated from the scourge of Takfiri terrorism.
On Tuesday, Syrian army forces, backed by allied fighters from popular defense groups, reached the eastern city of Dayr al-Zawr and broke a nearly three-year-long siege imposed by Daesh.
Shortly after breaking the siege, Syrian President Bashar al-Assad extended his congratulations to government troops on the major breakthrough against the Daesh Takfiri terrorist group
Daesh overran large parts of Dayr al-Zawr province, including its many oil fields, in mid-2014 as it seized areas in Syria and neighboring Iraq.
By early 2015, the Takfiri terrorists were in control of parts of Dayr al-Zawr city, and besieged the remaining parts of it under government control.
