"This airfield had been surrounded by ISIS [the former name of the Islamic State terrorist group] for two years,” Major General Igor Konashenkov, spokesman for the Russian defense ministry, said in a daily briefing. "Intelligence on the locations of the terrorist fire positions and support points around Kweires was provided by the Syrian opposition and cleared by the communication center in Baghdad.”
Lifting the siege on the airbase in Aleppo provinces has been one of the biggest victories for Damascus since Russia started providing air support for Syrian government forces.
The opposition also provided data to help target a big weapons depot of the Nusra Front, the Syrian branch of Al Qaeda, near the village Mheen in the Homs province, Konashenkov revealed.
Russia has been calling on moderate opposition forces in Syria to strike a truce with the government and fight together with it against the common terrorist threat.
Konashenkov reported that over the past two days Russian airplanes have conducted 85 combat sorties and attacked 277 targets in Syria. The airstrikes were conducted in the provinces Aleppo, Damascus, Latakia, Hama, Homs and Idlib, he said.
The general said intelligence from the opposition also helped the Russian air force to deliver a series of strikes around the city of Hama and prevented a planned offensive operation of the enemy.
