On Monday, Russian President Vladimir Putin said the demilitarized zone is to be established by October 15 and be 15-20 kilometers (9-12 miles) deep to separate Syrian forces and the rebels, with radical groups withdrawn from the area. But the Russian Defence Ministry said the Israeli warning came less than a minute before the strike, leaving the Russian aircraft in the line of fire. There was reportedly 14 military personnel on board of IL-20. The Syrian S-200 missile defense system was responding to a wave of strikes by four Israeli warplanes.
Konashenkov insisted the Israelis "could not but see the Russian plane, which was approaching the runway from an altitude of (3 miles)".
Many of those terror groups have the backing of Israel and its allies in their bid to topple the government of Syrian President Bashar al-Assad.
On Tuesday, however, Israeli army spokesperson Brig.
The Israeli military said its jets had targeted a Syrian site that was in the process of transferring weapons to Iran-backed Hizballah militants.
Defense Minister Avigdor Lieberman said Thursday he agrees with Putin that this was "a tragic mistake", but laid the blame on Syria.
Pompeo said the incident underscored the need to resolve "Iran's provocative transit of unsafe weapon systems through Syria, which are a threat to the region".
Late Monday, an Israeli raid hit Syria's coastal province of Latakia to prevent what it said were deliveries of materials for advanced weaponry to Hezbollah.
Russian Foreign Ministry spokeswoman Maria Zakharova on Thursday accused Israeli pilots of "unprofessionalism" and said that Russia still needs to hear more "explanations from Israel". He urged the Israeli side "not to allow such situations to happen again", according to the Kremlin.
"It will be the steps that everyone will notice", he said without elaboration.
Israeli Prime Minister Benjamin Netanyahu offered Russian Federation "all necessary information" to investigate.
But President Vladimir Putin, who spoke to his Israeli Prime Minister Benjamin Netanyahu by phone on Tuesday, then called it "a chain of tragic chance events" although he added that Russian Federation needed to "seriously get to the bottom of what happened".
Russian Federation has largely given Israel permission to strike targets in Syria on the condition that Jerusalem warns Moscow of the attacks.
A report from the Syrian Observatory for Human Rights, a pro-opposition watchdog based in the United Kingdom, on Monday estimated more than 113 members of Iranian forces and Tehran-backed militias had been killed in Israeli attacks in the last two months. Russian Federation says that its IL-20 spy plane with 15 servicemen aboard lost contact with radar near Khmeimim air base near Latakia.
[I] t also appeared as though the government and the Syrian opposition have different understandings of where the deal will lead, calling into question its chances for success. They started their target run at a low altitude from the Mediterranean Sea.
On the night of September 18, 2018, in an unfortunate incident, Syrian air defense mistakenly shot down a Russian military plane while the Syrian regime was targeting multiple missiles flying over Latakia.
Putin noted that this event is different from the November 2015 incident where a Turkish F-16 shot down a Russian Sukhoi Su-24 Fencer bomber when it briefly entered Turkish airspace.
