Moscow: Russia on Friday said the office of one of its energy companies was attacked in Syria by opposition forces it claimed were increasingly resorting to "terror" tactics.
The Foreign Ministry said the Stroytransgaz company`s office in the protest hub city of Homs came under gunfire on Thursday.
It reported no injuries but said security at all Russian facilities has been stepped up as a result.
"We believe that such terror methods deserve the firmest international condemnation," the Russian statement said.
Russia joined China on Tuesday in vetoing a UN Security Council resolution that threatened to impose "targeted measures" against Syrian President Bashar al-Assad for his crackdown on the opposition.
