The Guard said it launched the strikes on Sunday in retaliation for attacks in Tehran earlier this month that were claimed by the Islamic State group. Iran has been involved in Syria's long-running civil war, in which it has backed embattled Syrian President Bashar Assad.
Iranian state television quoted Gen Ramazan Sharif today as saying that "if they (IS) carry out a specific action to violate our security, definitely there will be more launches, with intensified strength."
But the missiles sent a message to more than just the extremists in Iraq and Syria, Sharif told state television in a telephone interview.
"The Saudis and Americans are especially receivers of this message." Said Sharif. "Obviously and clearly, some reactionary countries of the region, especially Saudi Arabia, had announced that they are trying to bring insecurity into Iran."

Deir el-Zour is home to both Islamic State militants and civilians. The extremists increasingly have fled to Deir el- Zour as the Islamic State group's de facto capital of Raqqa has come under punishing US-led airstrikes.
Five Islamic State-linked attackers stormed Iran's parliament and a shrine to revolutionary leader Ayatollah Ruhollah Khomeini on June 7, killing at least 18 people and wounding more than 50.
That attack marked the first to hit Iran, shocking its residents who believed the chaos engulfing the rest of the Middle East would not find them in the Shiite-majority nation.
The attack also came as emboldened Sunni Arab states - backed by US President Donald Trump - are hardening their stance against Iran. Since Trump took office, his administration has described putting Iran "on notice" over the missile tests and put new economic sanctions on those allegedly involved with the programme.
