A senior Iranian official says Israel will regret its "latest aggression" against Syria.
Said Jalili, the head of Iran's Supreme National Security Council, spoke on February 4 on a visit to Damascus.
His comments came a day after Israeli Defense Minister Ehud Barak implicitly confirmed Israeli war planes carried out an airstrike in Syria last week, saying it was "another proof that when we say something, we mean it."
U.S. officials have said the airstrike last Wednesday targeted a convoy carrying weapons near the Syria-Lebanon border.
Syria says it targeted a military research base near the capital.
Syrian President Bashar al-Assad, speaking during a meeting with Jalili on February 3, accused Israel of trying to destabilize Syria.
Iran is Syria's closest regional ally.
