Last month Moscow launched a bombing campaign against the twisted State terror group, which controls swathes of Syria and has forced thousands of people to flee the country.
Many desperate asylum seekers have made their way to Europe via boats to Greece.
But Russia’s bid to wipe out ISIS has been so successful that almost a million Syrians are elected to return to their homeland, Russian politician Dmitry Sablin claimed.
The senator, who recently visited Syria, said: "Syrian president Bashar al Assad praised the actions of the Russian Aerospace Forces in Syria."
"He said thousands of terrorists are now fleeing Syria, and refugees are returning."
Russian fighter jets have destroyed 285 ISIS and Al-Nusra Front targets in the war-torn country over the past three days, according to Russian media.
The Al-Nusra Front – the Syrian branch of Al-Qaeda – was formed in 2012 during the on-going Syrian civil war.
Putin’s military operation began on September 30.
