"In the last 24 hours, Russian jets conducted 82 sorties against 204 terrorist targets in Syria, located in the provinces of Aleppo, Idlib, Latakia, Hama and Homs. Furthermore, 32 of the sorties were conducted at night," the ministry's spokesman Maj. Gen. Igor Konashenkov said.
After the combat missions all aircraft have safely returned to the Hmeymim airbase, the spokesman added.
Since September 30, Russia has been conducting an aerial campaign in Syria against the Islamic State (ISIL, or Daesh in Arabic) extremist group, which is outlawed in Russia, following a request from President Bashar Assad.
A Russian Kilo-class submarine Rostov-on-Don located in the Mediterranean Sea launched a salvo of the Kalibr cruise missiles targeting terrorist positions, Konashenkov told journalists.
"For the first time ever, the Rostov-on-Don submarine launched a salvo of Kalibr cruise missiles from the Mediterranean Sea while submerged. The distinct characteristic of this launch was the fact that the missile salvo was fired from underwater via the torpedo tubes," he said.
