"The prime Minister said that the transfer of advanced weapons systems to irresponsible hands would increase the dangers in the region and that Israel would continue to defend its security and interest", a statement from the prime minister's office said Monday evening.
Russia, which fights in Syria to support the government, has said Syria shot the IL-20 surveillance plane down by mistake shortly after Israeli jets hit a nearby target.
In a phone call, Russian President Vladimir Putin told Israeli Prime Minister Benjamin Netanyahu that he disagreed with the Israeli version of events concerning the downing of the plane near Latakia, Syria last week, the Kremlin said.
Russia announced on Monday that it will supply the Syrian government with more modern, S-300 missile defence systems following last week's downing of a Russian plane by Syria, a friendly fire incident that sent regional tensions over the war-torn country soaring.
Russia's Tass news agency said at the time that the plane "disappeared during an attack by four Israeli F-16 jets on Syrian facilities in Latakia province". "This is an extremely ungrateful response to all that Russian Federation has done for Israel and the Israeli people recently", the DM spokesman said, suggesting "the Israeli military command either does not value the current level of relations with Russian Federation or does not control certain military units".
"This has pushed us to adopt adequate response measures directed at boosting the security of Russian troops" in Syria, Shoigu said in a televised statement.
Shoigu said Russian Federation will also jam military aircraft communications in the airspace next to Syria over the Mediterranean Sea, while upgrading Syria's air-defense command systems. "Now the situation has changed, and we are not to blame", the defense minister said.
Israel maintains that indiscriminate fire from Syrian forces was to blame for the incident.
Russian antiicraft missile systems - the S-300, right, and the S-400 - on display at a military industrial exhibition in Zhukovsky, in the Moscow region, on August 14, 2014. Liability falls on Israel, the ministry said, because warning of the strike came just one minute in advance.
The Israeli aircraft then continued to patrol the area off the Syrian coast, the radar data shows, refuting the claims by the Israeli Defense Forces that their planes had already returned to Israeli airspace at the moment of the incident. Foreign Minister Sergei Lavrov said the strikes had removed any moral obligation Russian Federation had to withhold the missiles and Russia's Kommersant daily cited unnamed military sources as saying deliveries might begin imminently.
The Russian government has agreed to provide the regime of Syrian President Bashar al-Assad with a missile defense system, according to the BBC. "The party responsible for the attacks in Syria and Lebanon and really the party responsible for the shooting down of the Russian plane is Iran", he said.
