Russia is using warships in the Caspian Sea to target the so-called 'Islamic State' state group in Syria, defence minister Sergei Shoigu said.
Russia last week began carrying out air strikes in Syria in what it said was a pre-emptive operation against terrorism in the Middle East.
Mr Shoigu told President Vladimir Putin in televised remarks that Russia this morning carried out 26 missile strikes from four warships of its Caspian Sea flotilla.
Mr Shoigu insisted the operation destroyed all the targets and did not launch any strikes upon civilian areas.
