European Union President Donald Tusk says signs have emerged that attacks on moderate opposition forces in Syria are creating a new flood of refugees.

Tusk told reporters at the G20 summit in Turkey on Sunday that such attacks will "only result (in) a new wave of refugees. And we have some signals that in fact it's started."

The U.S and its allies say Russian warplanes in Syria have mostly targeted moderate opponents of President Bashar Assad instead of their declared main target, the Islamic State group.

Russian President Vladimir Putin has dismissed the allegations.

Tusk did not mention Russia by name but said that the Islamic State is "the real enemy of the free world, not the moderate Syrian opposition."
