Iran's semi-official Mehr news agency reported on Sunday that a military adviser to Iran's Islamic Revolutionary Guard Corps (IRGC) died of his wounds after an Israeli air strike near the Syrian capital.

Israel has for years carried out attacks against what it says are Iran-linked targets in Syria, where Tehran's influence has grown since it began supporting President Bashar al-Assad after the 2011 revolution.

Iran says its officers are taking on an advisory role in Syria at the invitation of Damascus. Dozens of Revolutionary Guard members, including senior officers, have been killed in Syria during the war.

"Mekdad Macedani was wounded in the Zionist attack at dawn on Friday and was martyred," the agency said.

Friday's airstrike, Israel's sixth attack in Syria in March, killed Milad Heidari, another military adviser and Revolutionary Guard officer.

The Revolutionary Guards vowed to respond to Friday's attack.

The Iranian Revolutionary Guard announced two days ago – in a statement – the death of one of its military advisers, Milad Heidari, in the Israeli attacks that targeted the suburbs of Damascus at dawn on Friday, promising that Tehran "will undoubtedly respond to this crime," according to the statement.

The IRGC noted that the Israeli attack is a crime and a repeated violation of Syria's sovereignty as an independent state and a member of the United Nations.

The IRGC also denounced what it described as "the silence of the international community on Israel's crimes and repeated violations of Syrian sovereignty."
