"We carried out more than 300 combat missions in Syria in the past three days, hitting over 600 various targets," Russian Defense Minister Sergei Shoigu told Putin.
One video released by the Defense Department shows the massive airstrikes carried out by Long-range bombers.
Shoigu also said that the air force is strictly implementing Supreme Command's order to carry out combat missions in Syria alongside fighter jets, according to RIA Novosti.
The missions were carried out by Tu-22 long-range bombers and strike aircraft from the Russia air group.
The Russian military has also, for the first time, launched cruise missiles against terrorist targets in Syria from a submarine in the Mediterranean.
"We launched Kalibr cruise missiles from the Rostov-on-Don submarine in the Mediterranean Sea," Shoigu said, adding that the missiles were launched from a submerged position.
The Defense Minister also added that both Israel and the United States were informed about Russia's missile strikes in advance.
"I can confirm for you that we did get the notification of the airstrikes that were conducted by the Russians," US Defense Department Press Secretary Peter Cook confirmed, speaking to reporters on Tuesday.
Moscow has conducted airstrikes against Daesh in Syria since September 30, acting at the request of the legitimate government of Bashar al-Assad. Russian warships stationed in the Caspian Sea have also launched successful cruise missile strikes against the terrorist group.
