Moscow: Russia's military said on Sunday it had bombed 10 Islamic State targets in Syria over the past 24 hours in a further escalation of its campaign against the jihadist group.
"From the airbase of Hmeimim, the Russian aviation group is continuing to ramp up air strikes using high-precision missiles against the ISIS facilities in Syria," the defence ministry said.
"Over the past 24 hours SU-34, SU-24M and SU-25 jets made 20 sorties," the defence ministry said, reeling off the latest list of targets.
"Ten infrastructure targets of ISIS bandit groups have been struck," it said, using another name for IS, which is also known as ISIL or Daesh.
SU-25 jets attacked a training camp in Idlib province and "destroyed the terrorists' hideouts and a workshop making makeshift explosive devices including 'suicide belts'," the ministry said.
SU-24M and SU-34 bombers also hit eight IS facilities in the area of Jisr al-Shughur in Idlib province.
The defence ministry said the warplanes had once again deployed powerful concrete-buster munitions against IS targets.
"Four command posts of ISIS armed groups have been destroyed with the help of concrete-piercing BETAB-500 bombs," said the defence ministry.
A command post and ammunition depot were also bombed near the town of Maaret al-Numan in Idlib province.
And SU-34 bombers attacked an IS training camp and ammunition depot in Raqa province, dropping guided bombs and destroying the camp, the ministry said.
The base of Hmeimim is situated in Latakia province on the Mediterranean coast.
