The Russian Ministry of Defence said seven Kalibur cruise missiles were fired from submarines Velikiy Novgorod and Kolpino at targets around the city of Deir Ezzor, in Syria.
Russia has launched seven cruise missiles at ISIS targets around the city of Deir Ezzor in Syria.
The country's Ministry of Defence claims the Kalibur missiles were launched from two submarines, the Velikiy Novgorod and Kolpino, which are stationed in the eastern Mediterranean
The projectiles destroyed control centers, communication hubs and arms dumps being used by the terrorists, the regime said.
Russian stealth submarines Velikiy Novgorod and Kolpino launched seven cruise missiles toward ISIS targets around the Syrian city of Deir Ezzor on Thursday
Russia has been fighting in the region around Deir Ezzor for months alongside the forces of Syrian leader Bashar al-Assad in order to liberate the city from ISIS.
Last week the Syrian Arab Army fought its way to the outskirts of the city, breaking a three-year siege by ISIS.
Assad's forces are now attempting to drive the terrorists out of the city, which is one of their last strongholds in Syria.
American-backed Syrian Democratic Forces are also fighting near the city, advancing from the north bank of the Euphrates river, while Assad's forces move in from the south.
Kalibur missiles are Russia's answer to the American Tomahawks, capable of ranging up to 2,000km (1,200 miles) and carrying a payload of up to 1,000lbs.
Russian forces have been heavily involved in fighting around the city, where the army of ally Bashar al-Assad is fighting to oust ISIS
The Syrian Arab Army fought their way into the city last week, effectively ending a three-year ISIS siege, and is now battling to retake it entirely

The Velikiy Novgorod and Kolpino are two of Russia's latest Varshavyanka-class stealth submarines, and joined the Russian Black Sea fleet late last year.
The subs are powered by a mixture of diesel and electric engines, have a crew of 52 people each, and can patrol for up to 45 days without making port.
Advanced stealth technology is coupled with 18 torpedoes and eight cruise missiles, which Russia claims will allow the craft to strike land, sea and air targets.
Having lost its last stronghold of Mosul in Iraq earlier this year, ISIS now faces being wiped off the map in Syria as Russian-backed government forces push to take Deir Ezzor in the east, while the US-backed SDF advances into their 'capital' of Raqqa.
As their so-called Caliphate collapses, ISIS has launched and claimed responsibility for a series of terror attacks overseas, including three in Britain this summer.Read more at dailymail.co.uk
