Hezbollah chief Sayyed Hasan Nasrallah has briefed visiting Iranian official Ali Akbar Velayati on its battle in Syria's Qalamoun region, an Iranian news agency reported Tuesday. The two discussed recent developments in the region, and the spread of "takfiri groups," the report added. It said Nasrallah briefed Velayati, the foreign affairs adviser to Iran's Supreme Leader Ali Khamenei, on Hezbollah's ongoing battle alongside the Syrian army against jihadi groups in the border Qalamoun mountain range. Velayati in turn hailed Hezbollah's advancements in Qalamoun, and expressed optimism that "the resistance, which achieved great victories against the Zionist entity, will win in the battlefield like before." The visit came last in a series of meetings that Velayati held during his one-day trip to Lebanon Monday. He also met with Parliament Speaker Nabih Berri, Prime Minister Tammam Salam and Free Patriotic Movement leader Michel Aoun. Velayati served for 16 years as Iran's foreign minister, and currently heads the Center for Strategic Research, an Iranian think tank on strategy matters that was previously headed by Iranian President Hassan Rouhani. He also ran in Iran's 2013 presidential elections.
