Iranian President Ebrahim Raisi landed in Damascus Wednesday on the first visit by an Iranian head of state to the war-wracked country in over a decade. Tehran has been a main backer of President Bashar al-Assad's government since a peaceful uprising turned into a full-blown war in March 2011 and has played an instrumental role in turning the tide in his favor. Iran has sent scores of military advisers and thousands of Iran-backed fighters from around the Middle East to fight on Assad's side. With the help of Russia and Iran, Syrian government forces have controlled large parts of the country in recent years. During his two-day visit, Raisi is expected to meet Assad to sign several agreements and memorandums of understanding to boost cooperation, Syrian state and pro-government media reported. In an interview with pan-Arab television channel Al-Mayadeen, Raisi called for reconstruction efforts and for refugees who fled the country's war to return to the country. Raisi, who is a heading a high-ranking political and economic delegation, was received on arrival at Damascus International Airport by Syrian Economy Minister Samer al-Khalil. He is also set to visit the Sayida Zeinab and Sayida Ruqayya Shiite shrines, as well as the Tomb of the Unknown Soldier, a monument dedicated to Syrian soldiers killed in battle. The last Iranian president to visit Syria was President Mahmoud Ahmadinejad in 2010. The Iranian president's visit comes as some Arab countries, including Saudi Arabia and Egypt, have been opening up to Assad and their foreign ministers have visited Damascus in recent weeks. Syria’s foreign minister also visited the Saudi capital of Riyadh in April, the first such visit since the two countries cut relations in 2012. Syria was widely shunned by Arab governments over Assad’s brutal crackdown on protesters and the breakdown in relations culminated with Syria being ousted from the Arab League in 2011. The conflict has since killed nearly half a million people and displaced half of Syria’s pre-war population of 23 million. “America and its allies failed on all fronts against the resistance, and could not achieve any of their goals,” Iran’s new ambassador to Syria Hossein Akbari told Iran’s state news agency on Tuesday. Assad has visited Iran twice since the conflict began, the latest of which came in May last year. The Iranian president's visit also comes a week after its Minister for Road and Urban Development Mehrdad Bazrpash met Assad in Damascus, where he delivered a message from the Iranian president supporting the expansion of economic relations between the two countries, according to Iran’s state news agency. Iran’s military presence in Syria been a major concern for Israel, which has vowed to stop Iranian entrenchment along its northern border. Israel has carried out hundreds of strikes on targets in government-controlled parts of Syria in recent years — but rarely acknowledges them. Since the beginning of 2023, Syrian officials have attributed a dozen strikes on Syrian territory to Israel, the latest of which came early Tuesday and put the international airport of the northern city of Aleppo out of service.
