The top adviser to Iran’s supreme leader said he expects the Syrian army to soon recapture rebel-held Idlib province, as well as eastern Syria, an area where U.S.-backed militias hold swathes of territory. Iran is a close ally of Syrian President Bashar al-Assad and the Iranian official, Ali Akbar Velayati, was speaking in Aleppo, from which the Syrian army drove rebels after a siege last year with help from Tehran. The military alliance backing Assad, which also includes Russia and Shi‘ite Muslim militias, has this year focused on the war in central and eastern Syria against Islamic State (IS) militants.
