Russia's flights to Syria also carry military equipment

Russian "humanitarian" flights to Syria carry military equipment as well as humanitarian aid, Foreign Minister SergeiLavrov said on Thursday.

The United States and some European countries have expressed growing concern over the cargo on the flights.

Moscow has previously insisted in public that its flights to Syria are only humanitarian. Washington has put pressure on Greece and Bulgaria in recent days to deny Russia's requests to use their airspace for its Syria flights.
