According to official reports, the strike was launched at Islamic State targets near the UNESCO-protected ancient city of Palmyra - which has changed hands between ISIS and Syrian President Bashar al-Assad's Russian and Iranian-backed forces.
Russian military officials said the attack also destroyed command posts and large arms depots near Akerbat, in Hama Province.
Moscow said it warned American, Turkish and Israeli military officials prior to the launch.
