The sensational claim comes from Lieutenant General Sergey Rudskoy, a Russian defence chief, who said more than 150 cities and villages had been liberated from terrorists in Syria in recent weeks.
He said: ”A total of 311 sorties have been made over the first 10 days of 2016 during which strikes were delivered at 1,097 facilities.”
The jets hit oil facilities, infrastructure and equipment used by militants in the provinces of Aleppo, Idlib, Latakia, Hama, Homs, Damascus, Deir ez-Zor, Hasakeh, Deraa and Raqqa.
Mr Rudskoy added: "In December 2015, militants were driven from 134 cities and towns and from 19 settlements, with more in the first days of the new year.”

Russia’s attack squad comprises of more than 50 aircraft and helicopters, including the Sukhoi Su-34 and Su-24M bombers, Su-25 and Su-30SM fighters and Mil Mi-8 and Mi-24 helicopters.
The Kremlin approved bombing raids in Syria on September 30 after President Bashar al-Assad requested help in defeating ISIS - also known as Daesh.
But since then, Russia has been accused of targeting moderate rebels who are receiving backing from the West.
Separately, Mr Putin has told a German magazine he wants to work more closely with Europe and the US to defeat terrorism.

In a sign of thawing relations between Moscow and London, Berlin and Washington, he said: "We are faced with common threats, and we still want all countries, both in Europe and the whole world, to join their efforts to combat these threats.”
The highly-accurate rockets, which cost £100,000 each, have already been deployed to deadly effect in Iraq.
But the Prime Minister’s spokeswoman confirmed this morning that the RAF had carried out several air strikes against ISIS militants in Syria on Sunday, deploying the Brimstone for the first time there.
The missiles, which are designed to hit fast-moving targets and have already been used by Britain's Tornado jets in Afghanistan, Libya and Iraq, should bolster the fight against ISIS by delivering surgical strikes that minimise civilian casualties.
On Monday morning, an RAF Reaper flew the 1,000th drone sortie against ISIS since the beginning of operations in October 2014, the Ministry of Defence (MoD) said.
