Russian warplanes intensified their campaign against Islamic State targets near the ancient city of Palmyra, Moscow's Defense Ministry and monitoring groups said on November 2.
The Defense Ministry claimed to destroy a fortification, an underground bunker, and antiaircraft artillery in the raids, while monitoring groups said civilians and historic sites also were destroyed.
Rami Abdel Rahman, head of the Britain-based Syrian Observatory for Human Rights, and other activists said strikes hit the city's historic citadel, but the Russian ministry denied that.
Elsewhere in Homs Province, the observatory said at least 10 people were killed and more wounded in Russian strikes on Al-Qaryatain, an IS-held town.
Russia said its jets struck 237 targets in Syria over the past two days, including IS targets and Al-Qaeda affiliate Al-Nusra Front sites.
In Aleppo Province, Moscow said it hit a training camp for foreign fighters and a plant for making improvised explosive devices, and destroyed two armored vehicles in Hama Province.
Russia's military said it also struck a key Al-Nusra Front command post on a strategic hill in the coastal Latakia region.
