Iran's state-run media say the country's Islamic Revolutionary Guard Corps issued a statement on Saturday, saying four of its members were killed in an Israeli airstrike in Iran's ally Syria.

The statement says an Israeli fighter jet carried out the attack on a building in Syria's capital Damascus.

In December, Israeli airstrikes in Syria killed three members of the Revolutionary Guard Corps, including a senior adviser to the Guards.

The Revolutionary Guard Corps carried out retaliatory ballistic missile strikes on Tuesday targeting a base used by Israel's intelligence agency in northern Iraq.
