Hawzah News Agency (Moscow, Russia) - The missiles were launched from Russian navy frigates, the Admiral Essen and the Admiral Grigorovich, as well as a submarine, the Krasnodar, from the eastern Mediterranean, the Defense Ministry said in a Friday statement. The submarine fired its missiles while submerged. 

The strikes targeted ISIL command and control centers, as well as ammunition depots in the Syrian province of Hama.

Today’s precision strike hit a large ISIL ammunition depot near the town of Aqerbat, which detonated after receiving a direct hit, the Defense Ministry statement noted.

The remaining targets were destroyed in subsequent airstrikes, the ministry said. Russia warned Turkey and ‘Israel’ about the attacks via military-to-military hotlines, it added.

Over the past week, ISIL militants made numerous attempts to escape the besieged city of Raqqa and head towards Palmyra using a “southern corridor,” according to the Russian military.

The terrorists are moving forces through rugged terrain to the Hama province during the night and setting up command posts and ammunition depots in large buildings there, it added.

The movements of ISIL militants in the area are being monitored by Russian surveillance assets operating round the clock, the military said, adding that any potential targets detected will be subject to precision strikes by the Air Force.

Earlier in May, the same warships fired four cruise missiles that hit combat vehicles and militants outside the Syrian city of Palmyra (or "Tadmor" in Arabic).
