A senior foreign policy adviser to Iran's Supreme Leader has vowed to "stand by Syria's government" in the event of military aggression by the US and the wider coalition it is reportedly attempting to assemble.
Ali Velayati also said Iran backs Syria in its battle against the "Zionist Regime," referring to Israel.
"We will stand by Syria's government against any foreign aggression… Iran backs Syria in its fight against America and the Zionist Regime [Israel]," Ali Velayati told Iranian state TV during his visit to the East Ghouta region in Syria's capital on April 11.
Two Israeli warplanes attacked the T-4 airbase in the Homs governorate on April 9 according to the Russian Ministry of Defense, with both combat aircraft firing from Lebanese airspace to avoid Syrian air defenses, which downed an Israeli F-16 in February.
Syrian surface-to-air missiles (SAMs) reportedly intercepted around half of the missiles launched by Israel earlier this week.
However, the missiles which did reach their targets killed seven Iranian military personnel.
The Russian government has called for restraint and advised against hasty military intervention, as there is no evidence tying President Assad to the alleged incident.
