Russia, which fights in Syria to support the government against rebels and militants, has said Syrian anti-aircraft batteries shot the IL-20 surveillance plane down by mistake shortly after Israeli jets hit a nearby target.
The Russians furthermore claimed the IAF commander had lied about the location of the Israeli airstrike when he announced the assault would take place in northern Syria. Russian Federation laid the blame on Israel, saying Israeli fighter jets had pushed the plane into Syria's line of fire. Moreover, the Israelis misinformed the Russians about the location of their targets.
Israel disputes the Russian findings and says its jets were back in Israeli airspace when the plane was downed.
"There will be condemnation from "the West", but behind the scenes, the line between the Russians and Israelis will remain intact due to agreements they are both abiding by", Abboud told Al Jazeera from Pennsylvania in the US.
However, the radar data shows the Israeli jet fighters had continued to patrol the area off the Syrian coast following the incident, Konashenkov said.
Israel, "which is accustomed to launching many aggressions under different pretexts, will have to make accurate calculations if it thinks to attack Syria again", he said.
The destruction of an Il-20M radio-electronic surveillance aircraft with 15 crew members in the late evening of September 17 was not the worst tragedy in the records of the three years long Russian military intervention in Syria but it is perhaps the most hard one to explain away.
Israeli Prime Minister Benjamin Netanyahu has blamed Iranian paramilitary units in Syria of breaching its sovereignty by carrying out over-the-border attacks, and has vowed to keep acting against Iranian assets in Syria.
Alexander Khramchikhin of the Moscow-based Institute of Military and Political Analysis said the S-300 could "seriously affect Israel's ability to carry out its strikes in Syria".More news: Sen. Grassley slams Dems over handling of Kavanaugh confirmation, testimony underway

So next time Israel or the United States decides to strike Syria, it may not only find stiffer-than-usual resistance, it might find itself in a quickly escalating battle with one of the world's greatest military powers.
Russian President Vladimir Putin looks through the porthole while aboard the presidential plane on December 11, 2017, during the approach to the Russian air base in Hmeimim in the northwestern Syrian province of Latakia.
On Sunday, Moscow formally accused Israel of "an act of criminal negligence" by failing to inform Russian Federation of an imminent attack on targets in Syria.
Syria's Deputy Foreign Minister Faisal Mekdad said late Tuesday that the S-300 should have been given to Syria long ago.
Nevertheless, Netanyahu said that ultimately, Israel will continue to defend itself from Iranian escalation in the region, albeit preferably with Russian cooperation.
In deciding to provide Syria with the S-300 system, Russian Federation overrode years of Israeli opposition to supplying President Bashar Assad's regime with the technology.
But the Kremlin said "the information provided by the Israeli military. runs counter to conclusions of the Russian defence ministry", in a statement released on Monday after the phone call between Putin and Netanyahu.
The military said it will not stop its attacks against Iranian targets in Syria. It is possible that if another crisis develops in the future, they may be tempted to try to operate this new air force system, which is not impossible to deal with, but must be taken into account.
