Israel accuses Tehran of seeking to establish a foothold on its doorstep. Iran has vowed retaliation for an earlier alleged Israeli strike that killed a number of Iranian personnel. It said it intercepted most of the Israeli missiles.
Russian Federation was informed in advance of Israel's strikes, Conricus said.
"They need to remember the saying that if it rains on us, it'll storm on them".
Israel will no doubt strike back following any attack on its territory, a scenario that could spiral into a wider conflict that experts say no side is now interested in. "I hope we have finished with this round and that everybody understood", he added, calling on the Iranian regime to back down.
But the Britain-based Syrian Observatory for Human Rights, which has been monitoring the war in Syria, said at least 23 fighters were killed, including five Syrian soldiers.
Marandi said Iranians did not seem to have been among the casualties in Thursday morning's attacks.
"The targets belong to Soleimani's Quds Forces, and they are storages, command and control rooms, observation points, and some other operational sites", Brig. The attack also destroyed Syria's radar station, ammunition depot, and caused severe damage to Syria's air defense.
Israel, which said the drone it downed had been armed, carried out what it called "large-scale" raids on Syrian air defence systems and Iranian targets in the country. The broadcaster described the Israeli attack as "unprecedented" since the 1967 Mideast war.
Iran and Israel were already drawing deeper into confrontation before Trump pulled the United States out of the deal, but his move has shaken up the region. Israeli ministers have issued explicit warnings to Damascus several times in recent months, and hit the regime's air defense systems in Thursday's strikes. "There should be work to de-escalate the tensions", Deputy Foreign Minister Mikhail Bogdanov said, according to the TASS news agency.

Lt. Col. Jonathan Conricus, a military spokesman, said four of the rockets were intercepted, while the others fell short of their targets.

Thursday's exchange followed a suspected Israeli rocket strike in Syria on Tuesday on a military base in Kisweh, hours after Trump's announcement on the nuclear deal.
EU Commission boss Jean-Claude Juncker said Europe needs to "replace" the United States as a world superpower as the country "no longer wants to cooperate" to make peace with Tehran.
The attack late on Wednesday prompted Israel to launch attacks of its own against Iranian targets in Syria.
Israel blamed the initial missile strike on the Quds Force, which is a special forces unit of the Iranian Revolutionary Guard Corps.
Additionally, the Israeli government has accused Iran of providing weapons to militants from the Lebanese Shiite group Hezbollah.
If Israeli actions appear to threaten the stability of the Syrian regime, putting Russia's strategic position at risk, then Moscow might be willing to take a firmer stand against Israel.
He said Israeli troops remain on "very high alert".
But today was the first time Israel openly acknowledged targeting Iran.
