Russia began intervening directly in Syria's civil war in late September -- with air strikes in support of President Bashar al-Assad. While the strikes are halting rebel gains, they have not decisively tipped the war in his favor.
The conflict has already killed some 250,000 across the country.
Some 12 million people have been displaced and there is still no end in sight.
