Israel said it struck dozens of targets inside Syria overnight after a barrage of missiles was sacked by Iranian forces at the Golan Heights, a major escalation that edges the two Middle East foes closer to full-blown conflict.
However, the Syrian Observatory for Human Rights, a UK-based monitoring group, reported that the missiles struck weapons depots and missile launchers belonging to Iran's powerful Revolutionary Guards force.
Mr Conricus said Israel forewarned Russian Federation of its strikes on Thursday, which Syrian state media first reported hit Baath City in Quneitra, near the border.
Dozens of missiles were shot down by anti-aircraft systems in Syrian airspace.
Israel's strikes overnight were one of the country's largest aerial operations in decades across the Syrian frontier, and by far its broadest direct attack yet on Iranian assets.

Israel has warned Russian Federation and Syria not to intervene in its response.
In February, Israel accused Iranian forces at the T-4 base in central Syria of sending a drone into Israeli territory.
The Golan flare-up with Israel "is just further demonstration that the Iranian regime can not be trusted and another good reminder that the president made the right decision to get out of the Iran deal", White House press secretary Sarah Sanders told Fox News.
Tensions have been escalating between Israel and Iran in recent months.
Israeli Prime Minister Benjamin Netanyahu has traveled to Moscow where he and President Vladimir Putin will discuss military coordination amid new strikes in Syria blamed on Israel.
Any confrontation between Iran and Israel is likely to play out first and foremost on the battlefields of Syria, where Iran has built an extensive network of militias during Syria's civil war.
It then deployed defences and some reservists.
