Russian President Vladimir Putin said that he hopes nuclear weapons will not be needed after Russia launched cruise missiles from its submarine at ISIS targets in Syria.

During a meeting held between the Russian President and Russia’s Defence Minister Sergei Shoigu, Mr. Putin argued that they should analyze everything about what was happening on the battlefield and the weapons to be used.

“We must analyze everything happening on the battlefield, how the weapons operate. The Kalibrs (sea based cruise missiles) and KH-101 (airborne cruise missile) have proved to be modern and highly effective, and now we know it for sure – precision weapons that can be equipped with both conventional and special warheads, which are nuclear,” Putin said according to Russia Today.

“Naturally, this is not necessary when fighting terrorists and, I hope, will never be needed,” Russian president added.

On Tuesday, a Russian Kilo-class submarine, the Rostov-on-Don, launched Kalibr-PL cruise missiles against ISIS target for the first time.
