The Russian military has launched cruise missiles against Islamic State positions in Syria from both the Mediterranean and Caspian seas, one of which killed over 600 terrorists in the Deir Ex-Zor Province, Russian Defense Minister Sergey Shoigu has said.

Islamic State (IS, formerly ISIS/ISIL) have been suffering huge losses as a result of the Russian offensive, Shoigu said, adding that data on the ground shows that the flow of terrorists arriving in Syria has decreased, while more and more militants are fleeing the warzone to head north and south-west.
Over the past four days, Russian air forces have conducted 522 sorties, deploying more than 100 cruise missiles and 1,400 tons of bombs of various types, the minister stated.
He added that a strike on a target in Deir ez-Zor utilizing multiple cruise missiles had killed more than 600 militants.Shoigu stressed that the number of aircraft taking part in the operation has been doubled, and now consists of 69 jets conducting 143 sorties on a daily basis.
The minister pointed out that Russia is focused on destroying the terrorists’ economic base, having targeted 15 oil storage and refinery facilities as well as 525 oil trucks.
Russia has also destroyed 23 jihadists training camps, 19 plants producing explosives, 47 ammunition depots, as well as many other targets, according to the minister.
In addition, Russia’s air campaign has provided significant support for Syrian government troops near Aleppo, Idlib, Latakia and Palmyra, he noted.
He also added that the Russian military has begun cooperating with its French counterparts, as ordered by President Putin.
The Defense Ministry has published a video showing Russian servicemen at the Khmeimim airbase in Syria writing ‘For our people’ and ‘For Paris’ on bombs that were later dropped on the terrorists.
