Israel will regret its latest "aggression against Syria", according to Saeed Jalili, Tehran's security chief.
Speaking during a visit to Damascus, the Syrian capital, Mr Jalili, head of Iran's Supreme National Security Council, said: "Just like it regretted all its wars ... the Zionist entity will regret its aggression against Syria.
"The Syrian people and government are serious about this, and the Muslim world supports Syria.
"Syria is at the forefront of the Mus
world's confrontation with the Zionist entity," he added, in reference to Israel.
In Munich on Sunday, Ehud Barak, the Israeli defence minister, implicitly confirmed that the Jewish state had staged an air strike on Syria, following reports of an air raid which Damascus said targeted a military complex near the capital.
Mr Barak told the Munich Security Conference that the strike was "another proof that when we say something we mean it."
Wednesday's air strike targeted surface-to-air missiles and an adjacent military complex believed to house chemical agents, according to a US official.
Tehran has provided Syrian President Bashar al-Assad's regime with unequivocal support throughout the country's 22-month conflict, which the UN says has left more than 60,000 people dead.
Analysts have warned of the potential regional spillover of the conflict, which has divided the international community into two camps.
One Russia-led camp has backed Mr Assad, the other, led by the United States, has supported the revolt.
