Russian President Vladimir Putin has pledged continued military support for Syria’s Bashar al-Assad despite growing concerns over Moscow’s role in the war.
Putin urged other countries to join Russia in sending military-technical assistance.
He said the flow of refugees to Europe would have been “even bigger” without Russian support for Syria’s government.
But the White House said Russia’s support for President Assad was “counterproductive”.
The US would prefer to see more “constructive engagement” from Russia with the coalition against so-called Islamic State (IS), spokesman Josh Earnest said.
Moscow has been a key ally of Mr Assad throughout the bloody civil war, which began in 2011.
It says military equipment is being sent to Syria to help the government combat IS.
