Even if Iran had no intention of launching missiles at Israel on Tuesday, the alleged Israeli strike came along and conveyed the following message to the Iranians: You raised the likelihood of an attack on Israel, so we're raising the threat level, despite the tensions.Their reporter said that the issue now would be, "We're waiting to see what the Iranians will do: Will they continue the preparations for an attack" or stand down?
Also late on May 9th, Russian Television bannered, "Israel Launches Massive Missile Strikes in Syria" and opened:
Syrian air defenses have been deployed to thwart an attack by the Israeli rockets, Syria's state SANA news agency reported. The bombing is reportedly being carried out by Israeli warplanes from Lebanese airspace. ...Also late on May 9th, the New York Times reported that,
SANA has released footage of Syrian air defense systems responding to incoming missiles.
The Israeli strikes are seen as a continued retaliation to what Israel claims were some 20 rockets launched by Iran's Quds Force from Syrian territory into the Israeli-occupied part of the Golan Heights earlier in the night. The Israel Defense Forces said its Iron Dome systems intercepted some of the projectiles and the reported attack resulted in no injuries.
A missile strike, apparently by Israel, south of the Syrian capital, Damascus, on Tuesday [May 8th], an hour after Mr. Trump's announcement about the nuclear deal, killed 15 people, at least eight of them Iranians, the Syrian Observatory for Human Rights said on Wednesday.That alleged Israeli "missile strike" against Damascus on Tuesday - which Israel did not deny - could have been the provocation for the alleged retaliation against Israel by Iranians in Syria late on Wednesday May 9th, which could have provoked Israel's claimed "massive" missiles-retaliation soon thereafter.
That strike, on the area of Al Kiswa, targeted facilities for the Syrian military and their Iranian allies. Israeli news media said that one of the targets was a convoy of missiles taken out of storage and heading to a launching site, and that the strike was pre-emptive.
Comment: Others seem to think that the Syrians did respond by firing missiles into Golan: Syria and Iran establish new rules of engagement with Israel: Golan Heights no longer off limits
