According to the halturnerradioshow.com, nearly seven Ilyushin Il-76 military transporters of Russian Air Force have arrived at Khmeimim military airbase on 22 September.
The US political aide also blamed Iran for "attacks in Syria and Lebanon" and stated it was "really the party responsible for the shooting down of the Russian plane" last week.
"This is a very ungrateful response to everything Russian Federation has done for Israel".
The Russian deaths last week have forced Moscow to take "adequate retaliatory measures to increase the safety of its military fighting worldwide terrorism in Syria", Defence Minister Sergei Shoigu said in a televised address on Monday.
In an indirect warning at Israel, President Vladimir Putin's military said it would also start to jam the radar and satellite signals of planes that attack Syrian territory from the Mediterranean.
Russian Federation will provide advanced S-300 missile systems to Syria and directly link up with the air-defence network of its Middle Eastern ally, stepping up support for the regime of President Bashar al-Assad after the downing of a reconnaissance plane last week.

The dispute has increased tensions between Washington and Beijing , amid a brewing trade war between the two world powers. China's EED was added to the blacklist together with 33 Russian defense and intelligence officials and entities.
But after the downing of the plane last week, "the situation has changed", Defense Minister Sergei Shoigu said in an address carried live on national television. "It could cause a reaction by Israel or the USA, including attempts to destroy the system before it's operational".
A Russian Defense Ministry spokesman on Sunday stated that "objective data says that the actions of Israeli pilots, which led to the death of 15 Russian military personnel, point to either lack of professionalism or criminal negligence".
"The command posts of Syrian air defense forces and units will be equipped with automated control systems only supplied to the Russian armed forces". Then, "one minute" after Israel's call, its F-16 planes struck targets in Latakia in western Syria, he said.
The announcement came after Syria, which now uses the Soviet-era S-200 system, inadvertently shot down a Russian military plane on September 17. The Israeli leader also agreed with Putin on continued co-ordination between the two countries' armed forces.
Kremlin spokesman Dmitry Peskov later told journalists that the decision to supply the weapons was "not directed at any third country".
Putin and Syrian President Bashar al-Assad discussed the additional measures and delivery of the S-300 system on the phone on Monday, the Kremlin said.
Israel, by contrast, said that its air force hadn't violated any agreements with Russian Federation and that Israeli jets had already returned to Israeli airspace when the missiles were launched.
Russian Federation launched its campaign in support of President Bashar Assad in 2015, eventually turning the tide of war in favour of Syrian government forces.
