MOSCOW - Russia has never concealed the fact that it has been supplying military equipment to Syria aimed at fighting terrorism, RIA Novosti news agency cited a foreign ministry spokeswoman as saying on Monday. The agency, citing the ministry's spokeswoman Maria Zakharova, also reported that Foreign Minister Sergei Lavrov told US Secretary of State John Kerry in a phone conversation it is 'premature' to speak about Russia's participation in military operations in Syria.
