Russia's air force hit more than 60 terrorist targets in Syria over the past 24 hours, Moscow's military said Friday.

"Sixty-seven sorties have been carried out from the Hmeimim air base" in Syria, the deputy head of the Russian General Staff, Lieutenant General Igor Makushev, told reporters.

"Su-34M and Su-24SM warplanes hit 60 terrorist targets," he added.

According to intercepted radio communications, two high-ranking field commanders in the ranks of the Takfiri group, ISIL, and several hundred militants were killed, the Russian military said.

Makushev said militants "have sustained significant casualties and been forced to change their tactics," seeking refuge in towns and villages, stressing that Moscow would increase the intensity of the strikes.

On Wednesday, Russian warships from the Caspian Sea fleet joined in the strikes with a volley of cruise missiles launched from Caspian Sea.

Makushev said Russia has been bombing command posts and communication centers, ammunition depots as well as training camps in Raqa, Latakia, Hama, Idlib and Aleppo.

Moscow launched its military operation against ISIL(so-called Islamic State in Iraq and Levant)  terrorists at the request of the Syrian government on September 30.

Russia said its warplanes also dropped precision guided bombs on a command post in ISIL stronghold Raqa, killing two senior IS field commanders and some 200 militants.

The strikes also destroyed six command posts and communication centers, six ammunition depots, 17 training camps, three underground targets in Latakia, two multiple artillery rocket systems and 17 vehicles and armoured vehicles, among other targets, the military said.

"In the vicinity of Aleppo, a strike hit a militants' base and ammunition depot set up in the building of a former prison," Makushev.

"As a result, some 100 militants and an ammunition depot have been destroyed."
